The New York Giants aren’t amused by Odell Beckham Jr.’s continued end zone antics.

For those who missed it, Odell Beckham Jr. dropped to all fours and pretended to urinate like a dog after scoring a touchdown in the New York Giants 27-24 loss to the Philadelphia Eagles on Sunday. He was given a 15-yard penalty for the celebration.

That didn’t go unnoticed by one of the team’s co-owners, John Mara, who told Mike Vaccaro of the New York Post that he was unhappy with the situation.

“I do not want to get into a discussion about this,” Mara told Vaccaro via email Tuesday morning, “but I will say that I am very unhappy with Odell’s behavior on Sunday and we intend to deal with it internally.”

The Giants had hoped that Beckham would show more maturity this season, as he’s been flagged several times over his young career for stupid penalties and excessive celebrations.

It’s obvious that he hasn’t. For a guy who is hoping to become the NFL’s highest-paid player, you’d think he’d show some more self-discipline. Now, it appears as if the Giants may dispatch some of their own discipline instead.
