As football fans, we have come to expect various degrees of pissing and moaning from wide receivers when they aren't getting the ball. Call it the nature of the beast.

It usually happens on the sidelines, or in the locker room and now, like everything else, has found its way to Twitter.

Cardinals wide-receiver Larry Fitgerald, for the most part, has been one of the exceptions to the rule of bitchy receivers. His little brother, Marcus...not so much.

After Sunday's 31-17 victory over the Jacksonville Jaguars, Marcus Fitzgerald had some "tweets" for Cards' quarterback Kurt Warner.

In one "tweet," the less impressive Fitzgerald called Warner "an old ass man." In a

tweet posted after the game, Marcus posted this: "Just got off the phone with my brother. He's happy about the win. But PISSED he didn't get the ball thrown 2 him much!"

Fitzgerald caught four passes and had one touchdown in Sunday's victory, which is less than normal for Fitzgerald, but not nearly enough to get his baby bro's panties in a bunch.

Those comments have since been removed from the younger Fitzgerald's Twitter page and replaced with this: "I was just kidding about all that stuff," and, "I was just frustrated because as a brother I just wanna c him get the ball all the time ya know.''

Hold on to your convictions, Marcus!

We agree with you. Kurt Warner is an "old ass man," but that old-ass man somehow took the Arizona freaking Cardinals to the Super Bowl last year. Oh, not to mention he broke an NFL passing record in the very game lil' Marcus was whining about.
