Earlier, Vick admitted to participating in a dogfighting ring as part of a plea agreement with federal prosecutors in Virginia.
"Your admitted conduct was not only illegal, but also cruel and reprehensible. Your team, the NFL, and NFL fans have all been hurt by your actions," NFL Commissioner Roger Goodell said in a letter to Vick.
"The defendant will plead guilty because the defendant is in fact guilty of the charged offense," the plea agreement said.
"Most of the 'Bad Newz Kennels' operations and gambling monies were provided by Vick," the official summary of facts said. Gambling wins were generally split among co-conspirators Tony Taylor, Quanis Phillips and sometimes Purnell Peace, it continued.
"Vick did not gamble by placing side bets on any of the fights. Vick did not receive any of the proceeds from the purses that were won by 'Bad Newz Kennels.' "
Vick also agreed that "collective efforts" by him and two others caused the deaths of at least six dogs.
Around April, Vick, Peace and Phillips tested some dogs in fighting sessions at Vick's property in Virginia, the statement said. "Peace, Phillips and Vick agreed to the killing of approximately 6-8 dogs that did not perform well in 'testing' sessions at 1915 Moonlight Road and all of those dogs were killed by various methods, including hanging and drowning.
