The 49ers could be down to their third-string quarterback Thursday.
San Francisco signal caller C.J. Beathard is dealing with a sprained wrist he suffered in his team’s 18-15 Week 8 loss to the Cardinals. He was struggling to grip a football and didn’t practice Tuesday, according to the San Francisco Chronicle.
Coach Kyle Shanahan said he’ll be a game-time decision for the primetime matchup with the Raiders.
“C.J. would be good if we were playing on Sunday,” Shanahan said. “But it’s going to be a test for Thursday. And we probably won’t know until then.”
Beathard was inserted into the starting lineup after Jimmy Garoppolo tore his ACL in late September. Beathard has completed 60.4 percent of his passes and thrown eight touchdowns, along with seven interceptions, in six games this season.
Nick Mullens, an undrafted free agent out of Southern Mississippi who has never appeared in a regular-season game, would start in Beathard’s place.
“Nick’s a very smart guy who works at it nonstop,” Shanahan said. “And he’ll be able to go in there and execute the offense. He knows what he’s doing.”
The 49ers also have veteran quarterback Tom Savage, who they signed earlier this month, on their roster.
