Earlier this week, Rob Gronkowski pranked super agent Drew Rosenhaus by informing him he was signing with Jay-Z's Roc Nation Sports agency. According to the NFL Network's Albert Breer, Philadelphia Eagles wideout DeSean Jackson has split with Rosenhaus as his representation. This one's for real.

It's a little inexplicable considering Rosenhaus loaned Jackson money before negotiating his new five-year, $51 million deal prior to the 2012 season. However, Jackson's been known to spend copious amounts of time in the studio when he's not on the football field and being associated with Jay-Z could be a good look. Conversely, at this point it's all speculation, but it's every agents fear at this moment.
