The San Francisco 49ers suffered a heavy defeat on Sunday after star quarterback Jimmy Garoppolo was seriously injured, forcing him out of a game that ended in a 38-27 loss to the Kansas City Chiefs. at Arrowhead Stadium.

The 26-year-old quarterback, who signed a $ 137 million contract with the 49ers in February, could be out for the season after suffering an injury Sunday in an attempt to rally his team. The team fears that Garoppolo will tear his left anterior cruciate ligament.

Five minutes from the end of the match, the 49ers led 38-24 when Garoppolo led them in the final minutes.

The Chiefs' defense responded by sacking Garoppolo on consecutive games before taking it out of the pocket on the third goal of the 20-meter line. It is then that the San Francisco quarterback is headed to the sideline.

Garoppolo's left knee sagged just before the Chiefs' cornerback hit the shoulder, sending Garoppolo down. Garoppolo was on the grass for a few minutes before being helped to get up and finally failed in a 38-27 loss to Kansas City.

Justin Houston, a linebacker for the Chiefs, said it seemed that the quarter should have gone out of bounds rather than absorbing the blow.

"I think it was his fault," Houston told The New York Times. "I pray that he is not hurt, it's nothing serious, but as a quarterback, you have to go out of bounds. It's just an inch. An inch would not have made the difference. You have the meter. You must be smart. "

Garoppolo's ouster is the second loss to the 49ers after halfback Jerick McKinnon, who suffered a knee injury at the end of the season last month. The team has only two more quarters on the lineup.

Beathard succeeded Garoppolo with a little over five minutes, and he seemed to throw George Kittle a touchdown pass before the offensive pass interference erased him. San Francisco had to reverse a goal on the pitch and this was the last margin.

Top corner half Richard Sherman was injured in the calf, while Tarvarius Moore left with a wrist injury. A strong security Jaquiski Tartt was inactive with a shoulder injury and safety with his bare hands. Adrian Colbert is injured at the ankle, forcing a bunch of backups to play important snaps.

Still, the 49ers relied on semi-finalists Alfred Morris and Matt Breida and the strong arm of their quarterback to make a comeback. And after the move from Garoppolo to Marquis Goodwin in the third quarter, the score was 35-24, there was a sense of optimism on the sideline of San Francisco.

Beathard is about to start next week when the 49ers face the Chargers in Los Angeles, and Nick Mullens could get a call from the training team to serve as a backup.

Head coach Kyle Shanahan said Garoppolo would have an MRI on Monday to confirm that he had suffered an ACL tear.
