Texans safety Marcus Gilchrist was fined by the league office for his hit on Kansas City Chiefs tight end Travis Kelce.
Gilchrist plans to appeal.
Gilchrist was penalized for unnecessary roughness for his tackle on Kelce that caused a concussion.
During the collision that left Kelce woozy and forced him out of the game, Gilchrist's helmet made contact with Kelce's helmet as he was falling to the ground following a 26-yard reception.
