Keenan Allen suffered a right knee injury late in the first half against the Kansas City Chiefs and had to be carted off of the field.

Allen was ruled out for the game. He is scheduled to undergo an MRI on Monday.

Allen's right knee appeared to buckle as he came out of a break and he fell to the ground. Teammates gave Allen a hug as he left the field.

Allen had six catches for 63 yards before the injury.

Allen suffered a kidney laceration in the eighth game of 2015 and missed the rest of the season.
