Jackson owes ex-agent over $500K

An arbitrator on Tuesday ruled that DeSean Jackson owes former agent Drew Rosenhaus $516,415 in unpaid loans and fees, according to multiple media reports.

Yahoo! Sports reported Rosenhaus originally sought $777,793 for "loans, interest, credit card charges and insurance premiums." Rosenhaus filed the grievance in June 2013, shortly after he was fired by Jackson, according to reports.

Jackson intends on appealing the decision, which was handed down by arbitrator Roger Kaplan, the Philadelphia Inquirer reported.

After leaving Rosenhaus, Jackson signed with Joel Segal, who negotiated the receiver's three-year, $24 million contract ($16 million guaranteed) with the Washington Redskins that came days after his release by the Philadelphia Eagles.

Jackson, 27, had career highs of 82 catches and 1,332 yards as well as a career-high-tying nine touchdown catches last season, his first and last under Andy Reid successor Chip Kelly.
