49ers fear QB Garoppolo sustained season-ending ACL injury
KANSAS CITY, Mo. (AP) — The 49ers fear quarterback Jimmy Garoppolo will miss the remainder of the season after sustaining an injury to the ACL in his left knee late in Sunday's 38-27 loss to Kansas City . Garoppolo will have an MRI to confirm the severity of the injury, but 49ers coach Kyle Shanahan said "we fear an ACL." That would mean C.J. Beathard is in line to start at quarterback.
