San Francisco 49ers cornerback Richard Sherman remained in a walking boot Thursday.However he was adamant that his strained left calf is not related to his other more serious leg problems of the past year.Sherman hurt his calf in the second quarter of Sunday’s loss at Kansas City and didn’t return. Team officials said he’ll miss at least two games Y.A. Tittle Jersey , though Sherman said the only certainty was that he’d be sidelined for this Sunday’s road game against the Los Angeles Chargers.The three-time All-Pro missed the final seven games of last season after having surgery to repair a ruptured right Achilles tendon. But given that he also had surgery on his left Achilles during the offseason, Sherman was asked whether his current left leg injury might be connected to past issues.“It just makes it an easy story for you guys. Makes it lazy reporting,” Sherman said. “But nah, it’s getting back out there and going through the trials and tribulations of a season, wear and tear of football and taking all these reps after not taking them for eight months. Your body’s gotta get used to it again.”The 30-year-old Sherman missed a practice leading into the Chiefs game for what the team described as a “heel” issue, so he at least was on the injury radar even before Sunday.His absence is a damaging blow for a 49ers pass defense that ranks 27th in the NFL at 287.7 yards allowed per game. The Chargers enter Sunday ranked fifth in total offense (415.3 yards per game).Jimmie Ward, who has spent part of his career at safety, is expected to start in Sherman’s place. Second-year player Ahkello Witherspoon, who struggled two weeks ago against Detroit, likely will man the other cornerback spot.Compounding things is that both of San Francisco’s starting safeties, Adrian Colbert and Jaquiski Tartt, are battling injuries and their status is unknown for Sunday.But aside from health, the biggest issue for San Francisco’s defense has been poor tackling through the first three games. Defensive coordinator Robert Saleh said his unit is getting back to basics in practice, drilling on fundamentals even when the team is out of pads.“It’s very clear when you turn on the tape that we’re actually lunging and ducking our heads at the point of attack,” Saleh said. “When you teach tackling, everything that we talk about is you’ve got to run your body through their body.“Get a body on a body, step on their toes, wrap up, keep your feet moving, drive for five and get them to the ground.”The biggest culprits last Sunday were inside linebackers Reuben Foster and rookie Fred Warner, who missed six and four tackles respectively. Those two are believed to be a promising young core of the 49ers defense.But Sunday was Foster’s season debut after serving a two-game suspension. Saleh said Foster may have been knocking rust off, but the linebacker wasn’t letting himself off the hook.“That’s uncalled for, just missing tackles like that,” Foster said. “That’s not like us as a team and that’s not like me.”NOTES: Tartt (shoulder) missed Thursday’s practice as did guard Joshua Garnett (toe). Colbert (hip), running back Alfred Morris (knee) and guard Mike Person (knee) were limited. . Foster used “Roody-poo” in a quote earlier this week, a term made famous by “The Rock” during his wrestling days. Foster was delighted that the Hollywood star referenced it on Twitter. “It was amazing,” Foster said of the shout-out.<div class=”stanzacal” data-width=”100%” data-height=”250px” ></div> <script src=”https://dff2h0hbfv6w4.cloudfront.net/scr...stanzacal-v1.js” type=”text/javascript”></script> Let’s take a look back at how teams around the league fared on day 1 of the NFL Draft"WhiteFanposts Fanshots Sections 49ers Salary CapLevi’s Stadium Events49ers Transactions49ers Injury News49ers Press Conferences & Conference CallsNFL Draft2019 NFL Draft: 49ers picks Joe Montana Jersey , mock drafts, news, rumors, analysisWinners and losers from around the NFL on Day 1 of the draftNew,33commentsLet’s take a look back at how teams around the league fared on day 1 of the NFL DraftPDTShareTweetShareShareWinners and losers from around the NFL on Day 1 of the draftChristopher Hanewinckel-USA TODAY SportsIt’s hard to believe that NFL Draft is not only upon us but the first day is already in the books. We're going to take a moment to identify winners and losers from yesterday’s opening round because, well, we saw some really solid selections but also some head-scratchers (to put it lightly). Here are your “losers” and “winners” from the 1st round:LosersApr 25, 2019; Nashville, TN, USA; Daniel Jones (Duke) is selected as the number six overall pick to the New York Giants and poses for a photo with NFL commissioner Roger Goodell during the 2019 NFL Draft in Downtown Nashville. Mandatory Credit: Kirby LeeKirby Lee-USA TODAY SportsNew York GiantsDave Gettleman is calling the shots now in New York and, well, it’s safe to say that things are off to a rocky start. This offseason has provided the NYG fanbase with the opportunity to see the front office trade away arguably the best receiver in the league (while in his prime, mind you), took a $20 million cap hit in the process, and then selected Duke quarterback Daniel Jones with the 6th overall pick. That’s a way to do things.The Giants had a couple of other selections in the first round (Dexter Lawrence, DT, #17 and Deandre Baker, CB, #30) which may pan out but, if we’re being honest, this league is driven by quarterbacks. To make such a questionable selection that high when you still had the likes of Dwayne Haskins on the board (more on him later) and Drew Lock falling to round 2...it kind of just makes you wonder what New York is doing.Grade: C-Atlanta FalconsAnother collection of questionable picks in the first round for a team who could have honestly done better. The Falcons filled some holes on the offensive line by drafting Chris Lindstrom (OG, #14) and Kaleb McGary (OT, #31) - problem is, though, that they left some seemingly better talent on the board. Cody Ford and Jawaan Taylor could have both been had by Atlanta and would have been upgrades over Lindstrom and McGary. Obviously these prospects could develop into fine players but, as things stand now, it’s a swing and a miss for the Falcons.Grade: D+Arizona CardinalsWhen it comes to drafting in the NFL there is a balance between drafting for need and drafting the best-available player. If things go well then both of those things will line up and the player you select will fill a need and Deion Sanders Jersey , hopefully, will be the best player available on your board when it comes to your selection. Arizona, having the 1st overall pick in the NFL Draft, picked a player who may turn out to be fine but it’s hard to stop thinking about what could have been. Again, this a quarterback driven league so I understand the importance of getting “your guy” and, so, it appears as though new head coach Kliff Kingsbury has his in Kyler Murray. The thing is this is now the second year in a row the Cardinals have picked a quarterback in the top 10 of the draft. I’ve been watching Oklahoma football since I was a kid (Boomer Sooner) but, I've got to be honest: I never thought Murray was worthy of the first overall pick. Time will tell, but this one is iffy at best. And now they have to flip second year quarterback Josh Rosen for some value, which means that last year’s draft is now a bust.Grade: CWinnersWashingtonTalk about a day! There was talk of Washington trading up to #5 overall to snag Dwayne Haskins based on the idea that everyone thought that could have been an option for the Giants at #6. Not only did New York pass over him, but so did 10 other teams. Haskins fell to #15 which means that Jay Gruden got his guy and they didn’t even have to trade away draft assets to do it. Major victory right there. Also, trading back into the end of the first round to select highly-talented EDGE rusher Montez Sweat (#26 overall) definitely helps bolster what seems to now be a team on the rise.It’s going to be fun to see Haskins stick it to the Giants for the next decade or so.Grade: AApr 25, 2019; Nashville, TN, USA; Quinnen Williams (Alabama) is selected as the number three overall pick to the New York Jets in the first round of the 2019 NFL Draft in Downtown Nashville. Mandatory Credit: Christopher HanewinckelChristopher Hanewinckel-USA TODAY SportsNew York JetsMuch like San Francisco, there was talk that the Jets would have been interested in trading back in the draft. They didn’t, though, and that should be alright because they selected arguably the best player in the draft in defensive lineman Quinnen Williams out of Alabama. He could've gone #1 overall and nobody would’ve batted an eye. He now joins the ranks of an up-and-coming team looking to make its mark in a division that, outside of New England, is wide open.Grade: A+Denver BroncosJohn Elway drafted for the present by not selecting a quarterback at #10 overall. Personally I don’t think drafting quarterbacks in the first round has really suited him well. Instead, swapping their 1st rounder with Pittsburgh’s (#20 overall) also netted them a 2nd round pick this year and a 3rd round pick next year. Denver then, again, passed on a quarterback at #20 and went with one of the best receiving tight ends in the draft, Noah Fant. And guess what? Drew Lock is still available. So is Ryan Finley. I’d say Denver did a swell job in, like I said, drafting for the present but still giving themselves options to build for the future.Grade: A-What are your thoughts after day 1 of the NFL Draft?
