"Any time you lose your starting quarterback, that's a big deal", said head coach Kyle Shanahan. An MRI is scheduled for Monday.
Kansas City Chiefs defensive back Steven Nelson (20) closes in to tackle San Francisco 49ers quarterback Jimmy Garoppolo (10), right, during the second half of an NFL football game in Kansas City, Mo. "I haven't got a chance to see him yet, but I feel for him".
Garoppolo's left knee buckled just before the Chiefs' cornerback delivered a shoulder-to-shoulder blow, sending Garoppolo down. The quarterback was carted off the field. Mahomes achieved the distinction in the 2nd quarter of the ongoing matchup against the San Francisco 49ers, where outgoing QB Alex Smith started his career.
Exactly how this impacts the remainder of San Francisco's season is yet to be determined, although it can't look good.
Garoppolo wound up playing his best game of the season Sunday, throwing two touchdowns against zero interceptions, completing 66.6 percent of his passes and finishing with an impressive 114.7 passer rating, albeit against a suspect Chiefs defense.
Garoppolo appeared to sustain the injury prior to the collision.
"That was his fault", Houston said of the injury that occurred in the fourth quarter of the 38-27 Chiefs victory.
After the game, teammates wandered from the locker room into an adjacent training room to check on Garoppolo.
The 49ers went from 60-1 to 200-1 to win the Super Bowl, and 30-1 to 100-1 to win the NFC, at the Westgate Las Vegas SuperBook.
