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.

During a Tuesday appearance on KNBR, Kyle Shanahan said he believes Jimmy Garoppolo will be healthy enough to play in Week 7 against the Colts.

“I mean, he’s doing good,” Shanahan said, via 49ersWebZone.com. “We’ll see when we get back [after the bye week]. I think he’ll be ready to go next week when we get back. That’s the plan. I know he’s doing a lot better now than he was last week.”

Lance is dealing with a knee sprain he suffered while playing in place of Garoppolo in Sunday’s loss to the Cardinals. The team says Garoppolo will start again when healthy. The Niners have a bye in Week 6.

Kyle Shanahan says Trey Lance doesn't know when he injured knee. He had 16 carries. Prognosis: NOT a long-term injury, should be 1 to 2 week thing, but possibly just one week.

Jimmy Garoppolo may have better chance to return post-bye for Colts game but all TBD.

It's being called a left knee sprain, according to Inman. The 49ers have a bye in Week 6 and return to play the Colts in Week 7. The bad news is it's a Sunday night game, so owners will need a backup plan if they are counting on Lance or Garoppolo in Week 7. We likely won't know much more until next week.

San Francisco 49ers quarterback Jimmy Garoppolo missed Thursday's practice with a calf injury,

This marks two straight DNP's for Garoppolo. It is looking more and more like it will be Trey Lance under center this weekend against the Arizona Cardinals. There is still a chance Garoppolo practices tomorrow and tries to make a go of it against Arizona, so fantasy managers will want to monitor Friday's injury report before making plans to start Lance this weekend. Lance is currently our 14th ranked quarterback for Week 5.

As part of a mailbag question, someone asked what the game plan would look like with Trey Lance under center.

I expect it will be a “Back to the Future”-type situation for Kyle Shanahan and Mike McDaniel, who had rookies at quarterback (Robert Griffin III) and running back (Alfred Morris) when they were assistants in Washington in 2012. That team led the NFL in rushing and went to the playoffs. Morris finished with 1,613 rushing yards and Griffin with 815 yards.

The story said the one big difference is Lance attempted 318 passes at North Dakota State while Griffin attempted 1,192 throws at Baylor, which points more to a run-heavy attack. Anther issue is Sermon has only been OK as a runner over two games, and even if Mitchell returns from a shoulder injury, he's a rookie as well, so there are a lot of questions with the run game. The Niners do have the luxury of a bye in Week 6.

Jimmy Garoppolo "has a chance" to play for 49ers Sunday at Arizona.

The tweet went on to say HC Kyle Shanahan said, "It wasn’t as bad as we thought it might have been. Today he’s in a lot of pain and still sore. Wednesday if it’s getter better, he has a good chance." Earlier today there was a report that Garoppolo said the injury felt like someone stepped on his calf. He wasn't able to play in the second half in Week 4, giving way to Lance. Reports earlier today said Garoppolo could miss a couple weeks. The Niners do have a bye in Week 6.

It sounds like QB Jimmy Garoppolo is expecting to miss a couple of weeks with a calf injury.

Garoppolo and the 49ers explained the injury as feeling like someone stepped on the back of his calf. These injuries can linger, as Rapoport said. Rapoport added Jimmy G isn't always the same player when battling injuries in his career. So for now, it's Garoppolo to the bench and Lance will start. Of course reports over the last couple of days said the 49ers weren't prepared for Lance to play after taking over for Garoppolo during the second half of Week 4. The good news the staff should have him more prepared heading into Week 5. The Niners play the Cards in Week 5 and have a bye in Week 6.

49ers QB Jimmy Garoppolo told reporters Sunday that he will undergo an MRI on his calf.

He added: “I hope it’s just a couple of weeks or something.” Trey Lance threw two touchdowns in a losing effort against the Seahawks on 9/18 passing for 157 yards. After a 2-0 start, San Francisco has lost two straight and visit the red hot, 4-0 Arizona Cardinals next Sunday. The 49ers have their bye in Week 6, so perhaps Garoppolo could return for San Francisco’s Week 7 Sunday night game against the Colts.
