The San Francisco 49ers-Kansas City Chiefs game got ugly late in the fourth quarter, when tempers flared between 49ers tackle Trent Williams and Chiefs safety Bryan Cook.
The matchup had hardly been friendly up until this point, as the 49ers had previously gotten away with a dirty move on Patrick Mahomes in the third quarter. With the Chiefs up double-digits in the fourth, Williams appeared to be fed up with how the game was going and let out his frustrations on Cook.
