Brett Favre retired? Maybe not

Green Bay Packers quarterback Brett Favre, who announced his retirement last month after 17 seasons, could be weighing a comeback with another team.

According to NFL sources, Favre’s agent has quietly inquired with teams about their interest in trading for the three-time NFL most valuable player.

Favre, 38, has yet to give written notice of his retirement to the league or the players’ union, although that’s neither required nor irrevocable. It’s also not uncommon for players to delay in doing so, particularly if they are not in immediate need of their pension money.

Reached today, agent James “Bus” Cook said he was not aware of Favre’s interest in resuming his career.

“That’s news to me,” Cook said. “I don’t think that has anything to do with anything. He’s retired, period, point blank.”

Favre’s rights still belong to the Packers, who could trade him to another team.

The league sources said Favre’s decision to retire was partially influenced by his frustration that the Packers didn’t make a more aggressive attempt to sign Randy Moss. The team twice had a chance to do so, first in spring 2007 – before New England acquired the All-Pro receiver from Oakland – and again this off-season.

Favre retired a day after the Patriots re-signed Moss to a three-year, $27-million deal. Cook, who, along with agent Tim Dipiero, handles contracts for Moss, denied any link between the receiver and Favre’s decision to retire.

“As far as Randy’s deal with New England, there were never any negotiations with Green Bay,” he said. “As far as I know, Brett retired because he was tired and burned out.”
