Kansas City receiver Rashee Rice left the field on a cart with a knee injury after a bizarre play in which he was hit by Chiefs quarterback Patrick Mahomes while both players were pursuing Los Angeles

The Kansas City Chiefs pulled off a comeback win Sunday afternoon against the division rival Los Angeles Chargers, improving their record to 4-0 in the process. Early in the game, however, the Chiefs suffered a big loss: star wide receiver Rashee Rice left the game with a knee injury when Patrick Mahomes' helmet banged into the receiver's leg while Mahomes was trying to make a tackle.
