San Francisco 49ers top pick Nick Bosa left practice early on Tuesday, sustaining a hamstring during a pass-rushing drill and sitting out the remainder of workouts.

With the 49ers in their second day of a three-day week of organized team activities, Bosa did some 11-on-11 work, as well, before the injury forced the defensive end to limp off to the sidelines.

Head coach Kyle Shanahan told reporters afterward that the team does not yet know the severity of the injury, which happened while Bosa was working with the second-team defense, but Bosa remained out on the sidelines through the end of practice.

Bosa, 21, was selected second overall in April. He played in only three games as junior last season at Ohio State, suffering a core muscle injury in September and sitting out the remainder of the season to recover and prepare for the draft.

Shanahan also gave injury updates on his running backs, a position group with three players currently out.

Matt Breida suffered a slightly torn pectoral muscle during offseason lifting, Raheem Mostert had his fractured arm re-set because it was not healing properly, and Jerick McKinnon, coming off a torn ACL that cost him all of last season, is running lightly. All three are expected back for training camp, however.

On the bright side, quarterback Jimmy Garoppolo — also coming back from a torn ACL, his suffered in Week 3 last season — threw passes during 7-on-7 drills while wearing a knee brace. He won’t be cleared for full team drills until camp, Shanahan said.
