On Mother's Day, the New York Giants defensive end tweeted, "Happy Mothers Day Lesean Mccoy! Enjoy your special day!!"
Last summer, Umenyiora referred to the Eagles running back as "Lady Gaga" and "she" after McCoy tweeted that the defensive end is "overrated" and "soft" and the third-best defensive lineman on the Giants.
On Sunday, McCoy tweeted, "Lol let the beef begin."
Umenyiora recently joined Twitter and it didn't take him long to take a jab at McCoy. Umenyiora later tweeted to former teammate Brandon Jacobs, "u know the beef is never over. Never."
Umenyiora has said that he and McCoy have been going at each other for a long time, but the Eagles running back really drew his ire last summer with the "overrated" and "soft" tweets, which was in reference to news about Umenyiora's affidavit about general manager Jerry Reese allegedly promising him a raise as part of the players' lawsuit against the NFL during the lockout.
"I refer to him as she because that is something that a woman would do," Umenyiora told ESPNNewYork.com last June. "You can sit over there and be a Twitter gangster all you want to but on the football field is where you are supposed to address these types of things."
"I have always referred to him as that because he is woman," Umenyiora continued. "We have a lot of animosity toward each other personally and on the football field is where I thought it was left. But he has decided to take it off the football field and say some things that I just have no respect for."
