But we thought we played a great game today, and we’ll keep this momentum moving forward,” he said.Chiefs head coach Andy Reid told reporters: “You guys saw it.“The guy came up and hit JuJu for what looked like no reason.Dan Campbell (left) apologized while Reid (right) revealed Branch had done pretty good damage to his playerGettyMahomes, whose handshake was snubbed, wasn’t happy with the Lions’ behaviorGettyView Tweet: https://t.co/xt6KBj5pC3“I mean, we’re [in the middle of] taking a knee… yeah that’s tough. “But pretty good damage on JuJu’s nose.”Dan Campbell and Branch issue apology on behalf of LionsFollowing the incident, Lions head coach Dan Campbell condemned Branch’s actions and apologized to the Chiefs.“I love Brian Branch but what he did is inexcusable,” Campbell told reporters. “And it’s not gonna be accepted here. It’s not what we do, it’s not what we’re about. I apologize to Coach [Andy] Reid and the Chiefs and, you know, [Smith-]Schuster. That’s not OK. That’s not what we do here. And it’s not gonna be OK. He knows it. Our team knows it. That’s not what we do.”Branch also addressed his role in the melee.“I did a little childish thing,” he said. “But I’m tired of people doing stuff in between the plays and the ref don’t catch it, trying to bully me out there.“But I should’ve never did it. It was childish.”“I got blocked in the back illegally,” he said. “It was in front of the ref and the ref didn’t do anything. Just stuff like that. I could’ve gotten hurt off that. I still shouldn’t have done that.”Asked if he felt the Chiefs tried rubbing it in, Branch added, “It was a lot of stuff. But I should’ve shown it between the whistles. Not after the game. I apologized for that.”“I made a good block,” Smith-Schuster added. “He obviously responded after the game. At the end of the day, it’s about the team win.”The league has emphasized sportsmanship this season and it seems a foregone conclusion that Branch will be punished in some capacity.It wouldn’t be the first time either; Branch has already been fined three times this season and was fined seven times last season.In the end, the Chiefs had the last laugh, improving to 3-3 for the season while the Lions slipped to 4-2.Mahomes threw for 257 yards and three touchdowns, and scrambled for another score.Stay up to date with the latest from the NFL across all platforms – follow our dedicated talkSPORT USA Facebook page and subscribe to our talkSPORT USA YouTube channel for all the offseason news, interviews and more.
