49ers-Rams injury report: Patrick Willis, Tramaine Brock, Aaron Donald, Janoris Jenkins all questionable

The San Francisco 49ers and St. Louis Rams have released their final injury reports for Sunday's Week 9 matchup. The 49ers report features no surprises. Tramaine Brock and Patrick Willis were limited in Friday's practice, and are listed as questionable. Chris Culliver and Jimmie Ward were both full participants, and are listed as probable.

Willis spoke with the beat writers after practice and said he's still feeling pain in his big toe, and will be a game-time decision. If Willis is unable to go on Sunday, Chris Borland would get a second consecutive start at inside linebacker. He looked solid during the second half of the first Rams game, but then struggled against the Broncos (as did most of the defense).

Vic Fangio had said both Brock and Culliver were up in the air for Sunday, but with Culliver in as probable, he would seem likely to play. If that is the case, and Brock is also able to play, I suspect Brock would only work as a substitute in the nickel and dime packages. We will likely see Perrish Cox, Chris Culliver and Jimmie Ward as the first three cornerbacks.

The Rams injury report has cleared up a bit. Janoris Jenkins seems unlikely to play on Sunday, having sat out all three practices this week. Aaron Donald is a significant question mark with a shoulder injury. He sat out Wednesday and Thursday, but got some work in on Friday. I suspect he plays on Sunday, but if not, it would be a significant absence for the Rams.
