Nick Bosa injured his calf doing high knees during a personal warm-up before the 49ers’ Thursday walkthrough, coach Kyle Shanahan said. Shanahan estimated he could return in a few weeks but gave no firm timeline; a decision on injured reserve is pending.
Shanahan said it was unusual for the 49ers to have lost six of the 10 defensive linemen who made the team over the past two weeks. The article said the injuries left San Francisco with barely enough healthy players for a starting group and a couple of depth pieces.
Bosa is among several players being considered for injured reserve, Shanahan said. The team is weighing who may take longer to recover because it cannot place all of them there. The article said avoiding injured reserve would be a positive sign Bosa may not miss the four-game minimum; Shanahan said he expects Bosa back this season.
