ST. LOUIS — A sports agent from Ladue waited too long to sue Baltimore Ravens backup quarterback Robert Griffin III over hundreds of thousands of dollars in unpaid commissions, a federal judge in St. Louis ruled this week.

Ben Dogra sued Griffin last year, claiming he was owed for his share of marketing and endorsement deals from 2014 to 2016, deals that he negotiated on behalf of Griffin.

But U.S. District Judge Stephen R. Clark said Wednesday that a dispute between Dogra and his former employer, international sports and talent agency CAA Sports, and a reluctance by either Dogra or CAA to sue Griffin, meant Dogra had delayed the suit past the two-year statute of limitations that applied in the case.

After CAA fired Dogra in 2014, it arbitrated a series of disputes over the money owed Dogra, Clark wrote, including nearly $600,000 in marketing commissions.

After an arbitrator’s ruling in favor of Dogra on the marketing revenues, Griffin and his representatives were initially confused about who he should pay, Clark wrote. Neither CAA or Dogra wanted to sue Griffin when he later balked at paying, treating that idea like a “hot potato,” he wrote.
