49ers CB Emmanuel Moseley to miss 'a few weeks'

Moseley missed a pair of games to begin the year thanks to a knee injury, but he’s otherwise started all 10 games for San Francisco this season. The 25-year-old has been one of San Francisco's most reliable defensive backs, collecting 36 tackles and 10 passes defended. He was limited to only nine defensive snaps before exiting Sunday’s loss to the Seahawks. Rookie fifth-round pick Deommodore Lenoir saw the bulk of the snaps in Moseley’s stead, but he was eventually replaced by Dontae Johnson. The 49ers are also rostering third-round rookie Ambry Thomas.

More injury updates out of San Francisco: running back Elijah Mitchell is in concussion protocol after suffering symptoms Monday morning. The rookie standout briefly exited Sunday’s game before returning, and he finished the day with 84 yards from scrimmage and one touchdown. Mitchell has been the 49ers' leading back this season, and San Francisco might have to turn to Jeff Wilson if starter is forced to miss any time.

There was a scary moment for the 49ers on Sunday, when running back Trenton Cannon was forced to go to the hospital after suffering a concussion (via Matt Barrows of The Athletic on Twitter). While Cannon is in concussion protocol, the running back has been released from the hospital and is heading back to San Francisco, per Wagoner. The 27-year-old has spent most of his time on special teams this season, and he’s returned 16 kicks for San Francisco.
