I knew he wouldn't stay retired long...
Three days after a conference call with Green Bay Packers team officials on Tuesday in which quarterback Brett Favre emphatically expressed his desire to play in 2008, Favre on Friday formally asked for his contractual release from the Packers in a letter, sources close to Favre and the team said.
The letter was sent by Favre's agent, James "Bus" Cook, via overnight mail on Thursday and arrived at the Packers facility Friday morning.
Cook, on behalf of Favre, expressed a desire to have an amicable parting, as the Packers have been reluctant to embrace his return. Favre announced his retirement in early March.
During a conference call on Tuesday that included Packers general manager Ted Thompson, Packers coach Mike McCarthy, Favre and Cook, sources say that the quarterback stated emphatically that he wanted to play again.
