SANTA CLARA, Calif. (AP) — Coach Kyle Shanahan said Monday that Marshall native Trey Lance sprained his left knee during the 17-10 loss to the Arizona Cardinals and his status for when San Francisco returns from the bye next week remains up in the air.

Shanahan said Lance doesn’t remember when he hurt the knee, but felt it in bed Sunday night and underwent an MRI on Monday. The tests showed the sprain, but the injury is not considered serious.

Lance will remain in town during this week’s bye to rehab and will evaluated later in the week. The Niners should know early next week whether he has a chance to play after the bye against Indianapolis.

“It should be a one-to-two-week thing, but possibly just one,” Shanahan said.

Starter Jimmy Garoppolo also will be rehabbing his injured calf that sidelined him against the Cardinals and is expected to be able to play against the Colts.

Shanahan has maintained that Garoppolo is the starter when healthy, but was encouraged by what he saw from Lance in his first start since being drafted third overall.
