July 29 (Bloomberg) -- Brett Favre asked the National Football League for reinstatement today after announcing his retirement in March from the Green Bay Packers.

NFL spokesman Greg Aiello said in an e-mail that the league had received Favre's letter and that Commissioner Roger Goodell would ``take no action today.''

The 38-year-old Favre changed his mind about retiring earlier this month and asked to be traded or released by the Packers, who have prepared Aaron Rogers to take over as their starting quarterback.

The Packers said in a statement that they are aware that Favre sent his letter of reinstatement to the league and referred any questions to the commissioner's office. The team didn't comment further.

Packers General Manager Ted Thompson said yesterday he's had talks about trading Favre, who remains under contract with the team, while insisting the All-Pro quarterback won't be dealt to a division rival such as the Minnesota Vikings.

Thompson said that Favre, who holds NFL records for passes, passing yards, touchdowns and consecutive starts by a quarterback, also won't be released.

``To offer a blanket release relinquishing all of the club's rights to me doesn't make good business sense,'' Thompson said.

The New York Jets and Tampa Bay Buccaneers have expressed interest in Favre, ESPN said, and the player has also spoken with the Vikings. The Packers have asked the NFL to determine if there was any improper communication between Minnesota's coaches and Favre.

Goodell said yesterday that the league ``takes every tampering charge seriously'' and acknowledged he'd been asked to assist in the impasse between the Packers and Favre.

``These are decisions that the team and Brett are going to have to make individually based on what their desires are,'' Goodell said. ``The most important thing is that they're communicating properly and both understand what's important to one another.''
