The San Francisco 49ers are preparing for their finale when they host the Seattle Seahawks at Levi's Stadium on New Year's Day.

The 49ers will be without two offensive linemen. OG Andrew Tiller and C Marcus Martin, who have ankle injuries, did not practice yesterday or today and both were listed as out on the team's official injury report.

OT Joe Staley was among those listed as questionable for Sunday's game. The offensive lineman has been battling a hamstring injury that has sidelined him for the last three games.

"If I'm healthy, I'm 100 percent playing," Staley told Nick Wagoner of ESPN this week. "It just sucks sitting out. I've prided myself on being available to the football team every single week and had a nice little streak going there for a while. So it's kind of a bummer to sit out, especially with a hamstring injury. It feels good now, so I'm ready to go."

Two cornerbacks were also listed as questionable. They are Rashard Robinson and Dontae Johnson.

Below are the official injury reports for both the 49ers and the Seahawks as well as the Friday practice participation reports.
