The San Francisco 49ers and Detroit Lions released their final injury reports, and there are no surprises. Shaun Draughn and Marcus Martin both sat out the final day of practice, and were ruled out for Sunday. Other than Alex Boone and Michael Wilhoite, everybody else is listed as probable for Sunday.
Draughn's absence means we will see some combination of Kendall Gaskins and DuJuan Harris. The 49ers could decide to promote Jarryd Hayne as a third running back, but my guess is they see what they can do with just Gaskins and Harris. I suspect Bruce Ellington gets a few snaps in the backfield, as well.
Martin's absence means the center-right guard-right tackle combination will likely include Daniel Kilgore, Erik Pears, and Trenton Brown. Brown got extensive work last week once Martin got hurt, and he likely will get a full set of snaps on Sunday with Martin out. I wouldn't mind seeing Brown start the final two games, just to give us something to work with heading into the offseason.
