DeSean Jackson owes former agent Drew Rosenhaus $516,415 in unpaid loans and fees.

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.

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.
