Detroit Lions defensive back Brian Branch came clean about his "childish" behavior at the end of the team’s loss to the Kansas City Chiefs on Sunday night.

Branch punched Chiefs wide receiver JuJu Smith-Schuster after he snubbed Patrick Mahomes, who was going in for a handshake. It sparked a wild melee that ended with Smith-Schuster’s helmet off and players from both teams trying to separate the two.

Branch said he was upset with being blocked in the back by Smith-Schuster in the fourth quarter.

"I did a little childish thing, but I'm tired of people doing stuff in between the play and refs don't catch it," Branch said. "They be trying to bully me out there and I don't — I shouldn't have did it. It was childish."
