The 49ers are holding out some hope that starting quarterback Jimmy Garoppolo can return from his high-ankle sprain this week, which could make the rest of the depth chart a moot point.
“That’s something we’ll work through this week,” Shanahan said, via Matt Maiocco of NBCSportsBayArea.com. “I’m still not sure about Jimmy. Just finished [speaking] with the players about 30 minutes ago, so I don’t really know what we’ll do on Wednesday.
“We’ll have a plan by then. But [I] haven’t talked it over with the coaches, yet, so not sure.”
Mullens had shown competence in previous outings, to the extent that some wondered about Garoppolo’s long-term hold on the job. But his three-turnover outing against the Eagles caused the 49ers to go with Beathard for the last 5:42 of the game, and Beathard gave them a bit of a spark. The third-stringer played the final two possessions, and was 14-of-19 for 138 yards.
