The San Francisco 49ers announced a pair of roster moves on Tuesday. They have waived wide receiver Victor Bolden and cornerback Greg Mabin. The team made no corresponding roster moves, which leaves them with two open roster spots.
The two open roster spots will likely be for safety Marcell Harris and LB/DE Dekoda Watson. Harris is on the NFI list and Watson is injured reserve. Both had their practice windows activated, and are eligible to start playing this week. The team has until 1 p.m. PT on Thursday to activate the two of them.
Head coach Kyle Shanahan announced on Tuesday that Jaquiski Tartt (shoulder) is “probably doubtful” for Thursday and Antone Exum (concussion) is out. Defensive coordinator Robert Saleh said that Tyvis Powell would get the start at strong safety if Tartt and Exum did not play, but Harris would be the first guy off the bench behind him.
The 49ers linebacker depth chart could need Watson because of Reuben Foster’s hamstring injury. Malcolm Smith is currently playing the strong side linebacker position, but if Foster cannot go, Smith might move back to the weak side. If that happens, Watson could move in at SAM. Elijah Lee is an option at WILL as well.
Add all that to word that C.J. Beathard is not practicing on Tuesday, and the short week is a rough one for the 49ers.
