The Oakland Raiders confirmed Thursday that they have filed a grievance seeking to recoup money from former quarterback JaMarcus Russell.
A source with knowledge of the situation told NFL Network insider Jason La Canfora the team wants roughly $9.5 million.
Russell's agent, Eric Metz, didn't immediately return an e-mail from The Associated Press. He earlier told Yahoo! Sports, which first reported the story, that: "The money in question was fully guaranteed. That is why JaMarcus was forced to hold out and miss all of training camp as a rookie. The Raiders know that, and this is our only comment."
According to La Canfora, one source dubbed the potential ruling in the case as "50/50," depending on the interpretation of some language in Russell's contract. Russell was paid salary advances for the 2010, 2011 and 2012 seasons.
