Giants tackle Ereck Flowers apologized to an ESPN reporter for pushing him away in the locker room Sunday night in Green Bay after a 23-16 loss to the Packers.

“I talked to Ereck, Jerry [Reese] talked to Ereck, and P.R. talked to Ereck,” Ben McAdoo said during a conference call Monday. “We had a chance to sit him down. He called and spoke to Jordan [Ranaan, the reporter] and apologized. He understands that he cannot behave that way. It’s unacceptable. It’s important for us all to have a professional relationship with the media, players and coaches.”

McAdoo would not say if Flowers will face any discipline from the team, saying all such decisions will be “handled in-house.”

The brief incident occurred after Flowers struggled in the game, allowing numerous hits on Giants quarterback Eli Manning. It also followed a week of heavy scrutiny of the Giants because of the behavior of Odell Beckham Jr., who threw a sideline tantrum in Week 3 and drew a taunting penalty in Week 4. Beckham played without incident Sunday night — he even caught his first touchdown pass of the season — but the situations feed the perception of a team that lacks self-control and discipline.

McAdoo disagreed with that.

“I think it’s an isolated incident,” he said of Flowers. “There are signs of discipline and signs of things we need to clean up . . . It’s an emotional game. We have emotional players. There are no excuses.”

As for Flowers’ play as a second-year left tackle, McAdoo put him together with the entire offensive line.

“This week, we took a step backwards,” he said of the group. “You learn from it, you watch the film, you address it. You’re brutally honest with each other and you have to move on. That’s the way this thing is. You’re not going to play great every week. There are going to be peaks and there are going to be valleys. When you hit the valleys, you have to learn from them, correct the mistakes and move on.”
