Kansas City Chiefs tight end Travis Kelce is tackled by Atlanta Falcons Foyesade Oluokun during the first half of an NFL football game, Sunday, Dec. 27, 2020, in Kansas City.

The Falcons (4-11) took the lead when Matt Ryan hit Laquon Treadwell for a 5-yard touchdown with 4:33 to go. Kansas City finally took its first lead on Harrison Butker's 53-yard field goal with 14:08 left in the game. The Falcons squandered their first chance to match the points when Brandon Powell coughed up the ball deep in Kansas City territory.
