Niners head coach Kyle Shanahan said Monday that wide receiver
Deebo Samuel (groin) and linebacker
Fred Warner (hamstring) are each likely to miss Week 13's game
against the host Seattle Seahawks and Samuel could also miss another game.
Shanahan said Warner was likely out for Sunday, while Samuel was expected to miss one to two weeks.
Samuel, who's been a dynamic force for the 49ers offense as a receiver and rusher, strained his groin, per Shanahan, against the Vikings and left the game in the second half. NFL Network Insider Ian Rapoport reported earlier Monday that Samuel was set for an MRI and was expected to miss some time, but it wasn't considered a major injury.
