The Facts: The 49ers fear that quarterback Jimmy Garoppolo suffered a torn ACL during Sunday's loss to the Chiefs.

Diehards Line:The injury occurred while Garoppolo was running down the sidelines and it was a non-contact injury. He was carted off of the field and initial reports suggest it could be a season ending injury. He will undergo an MRI on Monday, but at this time fantasy owners should already be preparing to be without Garoppolo. C.J. Beathard is the next man up.
