The nightmarish Sunday for Odell Beckham Jr. was worse than we thought.

Beckham embarrassed himself and the Giants organization on Sunday against the unbeaten Panthers, throwing tantrums and getting himself into trouble. The explosive receiver was marginalized during the game and his frustrations with Carolina cornerback Josh Norman boiled over.

Odell Beckham's Apology Not Sincere

The 2014 Offensive Rookie of the Year was flagged for three personal foul penalties on Sunday, the worst of which came after he nailed Norman with a dangerous helmet-to-helmet hit. Beckham questionably remained in the game, but was eventually suspended for this Sunday's game against the Vikings.

After his appeal was heard and denied by the league, Beckham issued a seemingly heartfelt apology on Twitter. It turns out, he likely has some more apologizing to do.

Just when it appeared as though Beckham couldn't have looked any worse, "Inside The NFL" released a video that showed the flashy receiver barking at teammates and throwing a tantrum on the sideline.

"We're getting our asses kicked and y'all don't care," Beckham yelled at teammates in the video.

The receiver also screamed at his fellow Giants teammates to "get the f--k up."

Maybe it makes Beckham look like a crybaby, but the second-year star's message may have made an impression on his teammates.

After the tangent, the Giants orchestrated a comeback from a 35-7 hole and tied the game up, only to fall to the Panthers on a late field-goal.
