San Francisco 49ers quarterback Jimmy Garoppolo is battling an injury that could force him to miss this Sunday's matchup against the Houston Texans. On Monday, head coach Kyle Shanahan told reporters that Garoppolo sprained his thumb when he was sacked during their 20-17 loss to the Tennessee Titans on Thursday night.

ESPN's Adam Schefter is reporting the injury could be more serious than just a sprain. Jimmy G sat out on Monday and the team said they will see where he is on Wednesday. The Niners are in the playoff hunt and host the Texans in a later afternoon game on Sunday.

49ers QB Trey Lance (knee) will back up Jimmy Garoppolo Week 8 at Chicago after being removed from the team's injury report.

Lance will officially be around in case Jimmy G fails to get the offense going against the Bears. That said Lance is not worth starting until he replaces the veteran.

49ers QB Trey Lance (knee) was limited in practice Wednesday after missing Week 7.

Jimmy G looked okay at best Monday night, giving Lance a little more of a chance to at least steal snaps under center Week 8 at Chicago.

Trey Lance is on pace to be able to practice on Wednesday, but Kyle Shanahan says that Jimmy Garoppolo will start at Chicago.

Shanahan said he did not go into game thinking that if Garoppolo had one bad game, he would not be the starter any longer, according to other reports. And Shanahan indicated Lance, when healthy, won’t be getting more first-team reps during practice, adding, “You’re not going to start rotating quarterbacks because it’s not an open competition right now.”

49ers head coach Kyle Shanahan was asked if Jimmy Garoppolo would start again in Week 8 against the Bears.

“I would guess so,” Shanahan said, via Jennifer Lee Chan of NBCSportsBayArea.com. “I will watch this tape and see if guys are healthy, first of all, and know where our guys are at. It was good for Jimmy to get healthy enough to play in this game today.”

While it doesn't seem like a confident answer, the story did say Shanahan added that he didn’t see “a ton of bad decisions” from Garoppolo. But the story added there weren’t enough good things either and that will keep questions about the quarterback spot front and center for the 49ers. It could be an interesting decision when Lance is healthy enough to play.

49ers QB Jimmy Garoppolo (calf) will start Week 7 against the Indianapolis Colts. QB Trey Lance (knee) will not be active.

Do not expect a lot from Garoppolo if the weather is as bad as it sounds, including torrential rain.

San Francisco 49ers quarterback Trey Lance missed another practice with a knee injury.

The 49ers will play it safe with Lance, especially with Jimmy Garoppolo (calf) healthy enough to be a limited participant in practice. Jimmy G should get the start in Week 7, and barring injury, will likely continue to start until Lance proves he is ready to take over. Jimmy G is our 19th ranked quarterback for Week 7.

49ers QB Jimmy Garoppolo (calf) was limited at practice Wednesday, while Trey Lance (knee) did not participate. 49ers HC Kyle Shanahan wants to limit Garoppolo so he can be a full-go Sunday against the Colts.

It looks like Jimmy G is the go-to QB for now, but Lance, when healthy, will have his plays.

According to multiple reporters at the team’s Monday practice session, Jimmy Garoppolo was on the field but Trey Lance was not.

The 49ers will not issue an injury report until Wednesday, so they don’t have to share either player’s participation level on Monday, the story said. Garoppolo is dealing with a calf injury while Lance has a knee injury. Before the team's bye, the Niners said they expected Jimmy G to be ready for Week 7 and at this point he seems on track.
