The San Francisco 49ers have lost four straight games, leading to questions about Jimmy Garoppolo's status as the team's starting quarterback.

After Sunday night's 30-18 loss to the Indianapolis Colts, Kyle Shanahan sounded less sure about Garoppolo than at any point this season.

"I would guess so," Shanahan said when asked if Garoppolo would start in Week 8 against the Chicago Bears. "I'll watch this tape and see if guys are healthy, first of all."
