The San Francisco 49ers have yet to choose between C.J. Beathard and Jimmy Garoppolo as their starting quarterback this week.

Kyle Shanahan said Beathard is "pretty banged up." He suffered a bruised left knee and hip strain this past Sunday.

"I will probably have an answer for you guys on Wednesday," Shanahan said. "I'd like to talk about it [with] the staff, I'd like to watch some Chicago first. We just finished up Seattle, just finished up watching the game with the quarterbacks, then came in here -- but I'll have a decision for you guys by Wednesday."
