SANTA CLARA https://www.49ersfanshop.com/Jerry-Rice-Jersey , Calif. (AP) — Two key San Francisco 49ers defensive players are sidelined from injuries during the offseason program.The 49ers said that safety Jimmie Ward broke his collarbone at practice on Thursday and that first-round defensive end Nick Bosa has been diagnosed with a grade 1 hamstring strain.Ward is expected to miss at least eight to 12 weeks but should be healed by the start of the season. Bosa will need a few weeks to recover and will likely be out for the rest of the offseason program that ends June 13 but ready for training camp in July. Bosa hurt his hamstring during practice on Tuesday.Ward had been working with the starters at free safety this offseason after signing a one-year contract with $3 million guaranteed and $1.5 million in roster bonuses in free agency. Ward was picked in the first round in 2014 but has played only 51 games in five seasons, ending four of them on injured reserve with broken bones. He also broke his collarbone in 2016.With Ward sidelined, Adrian Colbert will likely take his spot as starter during practices this offseason. Colbert was a seventh-round pick in 2017 and became a starter at free safety halfway through that season after Ward broke his forearm. Colbert began the following year as starter but went down with a season-ending ankle injury in October.Bosa was picked second overall by the 49ers despite going down with a season-ending core muscle injury in his third game last season for Ohio State. Bosa was part of a major upgrade this offseason to San Francisco’s pass rush, along with defensive end Dee Ford. Neglecting to add a backup to Bosa and Ford could come back to haunt the Niners." />Skip to main contentclockmenumore-arrownoyesHorizontal - WhiteNiners Nationa San Francisco 49ers communityLog In or Sign UpLog InSign UpFanpostsFanshotsSectionsLibrary49ersOddsShopAboutMastheadCommunity GuidelinesStubHubMoreAll 322 blogs on Horizontal - WhiteFanposts Fanshots Sections 49ers Salary CapLevi’s Stadium Events49ers Transactions49ers Injury News49ers Press Conferences & Conference CallsFiled under:San Francisco 49ers NewsMy least favorite offseason move by the 49ersNew,91commentsNeglecting to add a backup to Bosa and Ford could come back to haunt the Niners.PDTShareTweetShareShareMy least favorite offseason move by the 49ersPhoto by Lachlan Cunningham/Getty ImagesThe San Francisco 49ers have been the media darlings this offseason after trading for Dee Ford, drafting Nick Bosa Colin Kaepernick Jersey , and making a few other moves that will put them in a position to compete for a playoff spot in 2019. The team needed a pass-rush. They added that. The Niners also needed to inject some athleticism into the wide receiver group, and they did that as well. Tackling the two most significant needs while adding some much-needed depth at key positions that suffered injuries during 2018 will reflect in the win/loss column right away.We talk every other day about the safety position. I believe that if Tarvarius Moore is indeed staying put at free safety that the team will also reap those benefits sooner than later. There were a couple of questionable signings this offseason, and that’s going to happen with every team. The signing that bothered me the most was the one that never happened.Fundamental four Going through the team leaders in pressure rate on defense last year, and I noticed the top teams all had something in common. They had one—if not two—players with at least 30 pressures, and two players in the mid-’20s. The Los Angeles Rams were number one because of Aaron Donald. They also had Ndamukong Suh, who had 30 pressures Richard Sherman Color Rush Jersey , and both of their starting edge rushers had over 26 pressures. The Pittsburgh Steelers may be a better example as since they don’t have the most dominant player in football. Cameron Heyward and T.J. Watt were both over 33 pressures. Bud Dupree and Stephon Tuitt both produced into the mid-’20s. This was the case for the majority of the teams that were in the top-10 in getting after the quarterback last year.Deforest Buckner led the team with 29.5 pressures. After that? Cassius Marsh with 20. The addition of the Bosa and Ford duo is a significant upgrade. If the numbers from last year are any indication, the 49ers still need one more pass-rusher. Could that be Arik Armstead, Solomon Thomas, or another unknown? The 49ers are depending on someone to step up.I liked a lot of the signings more than most. I do believe Kwon Alexander will be able to make an impact. I also think Tevin Coleman will surprise many with his game-breaking ability. When the team continued to add depth, it made sense. When they ignored a third pass-rusher after cutting Marsh, I was confused. You’re asking players to step up and contribute in ways they haven’t shown in the NFL. Will things be easier for the role players now that they are in a position to be https://www.49ersfanshop.com/Jaquiski-Tartt-Jersey , you know, actual role players? That’s a safe bet. It’s not an easy task to increase your production significantly, despite the changes that have been made to the roster.Electing to ignore the secondary would have made more sense if the team was able to replace Marsh. Go through each of the top defenses depth charts. They all have four guys that proved they can pressure the quarterback last year. The 49ers have three. Finding that fourth option will be imperative to their success.
