Many 49ers are not healthy as the team goes through its OTAs. In addition to the likes of Jerick McKinnon, Weston Richburg, Jason Verrett and Kwon Alexander, the team lost one of its running backs because of a weightlifting injury. The 49ers will not have Matt Breida available until at least training camp. The running back, who battled maladies last season before ending the year on IR, suffered a partially torn pectoral muscle while lifting recently, Matt Maiocco of NBC Sports Bay Area notes. San Francisco is already without McKinnon and backup Raheem Mostert, who is battling for a roster spot now that the team employs Tevin Coleman. While torn pectorals of any kind are obviously a concern, Kyle Shanahan said Breida will not require surgery. But the 49ers’ optimal backfield still has a ways to go before coming together.

Here is the latest from the NFL’s Bay Area teams, in their final offseason sharing a region.

• While Breida is expected to return before the start of the regular season, Garrett Celek‘s timeline is more concerning. The eighth-year 49ers tight end suffered a concussion in Week 16 last season and has yet to be cleared from concussion protocol, according to Shanahan. Celek is also dealing with a back injury. The soon-to-be 31-year-old tight end resides as the 49ers’ second-longest-tenured player, having been with the team since 2012. The 49ers did draft Kaden Smith in the sixth round but, beyond Celek, do not have much at tight end behind George Kittle.
• Jimmie Ward‘s injury likely will not keep him out for the rumored three-month span, with Maiocco believing that to be on the cautious side of the safety’s timeline. Should they get Ward back by training camp, the 49ers are not likely to sign a veteran safety — like Eric Berry or Tre Boston — to replace Ward, Maiocco adds. Although Ward is back on only a one-year deal, the 49ers believe he is their best defensive back when healthy. On a team that employs Richard Sherman, that’s certainly a notable distinction.
• The Jon Gruden–Mike Mayock regime reshuffled their front office and scouting staff recently. The roles of recently hired staffers Dwayne Joseph, DuJuan Daniels and Walter Juliff are now known. Daniels, who joined the Raiders after a Patriots tenure, is now Mayock’s assistant director of player personnel. Joseph, who came over from the Eagles, will become the Raiders’ director of pro personnel. A former Cowboys exec, Juliff is now a senior advisor to the GM, NBC Sports Bay Area’s Scott Bair tweets. Recently with the Senior Bowl and the Bills, Jack Gilmore is now in place as Raiders scouting coordinator. The Raiders also hired recent Eagles scouting coordinator John Hill as a pro scout. Lastly, Oakland promoted Trey Scott and Teddy Atlas (not that one) to assistant player personnel director and assistant director of college scouting, respectively. Scott was one of the few staffers to help with the Raiders’ draft, after Mayock dismissed the scouts prior to draft weekend.
