NFL Players Association lawyers argue that the league's collective bargaining agreement protects Michael Vick from the Atlanta Falcons' attempts to be refunded up to $22 million in bonus money.

The Falcons feel the suspended quarterback knew he was in violation of the contract when he signed the $130 million deal in December of 2004, and that he used proceeds from the deal to fund his dogfighting operation.

According to the University of Pennsylvania law professor and special master who led the arbitration hearing, a decision is expected by October 12.

Vick has admitted helping to kill six to eight dogs, among other things, and pleaded guilty to a federal conspiracy charge August 27. He faces up to five years in prison when he's sentenced December 10 on the federal charges. He's also facing state felony charges in Virginia.
