"He's retired, he doesn't have any desire to come back, and that's the way it is with Brett," Cook said. "He's mowing his grass. He's working on his farm. He enjoys that stuff."
Cook said he originally asked the Jets to release Favre after the season as just "the order of business. Brett wants to retire as a Packer and that's just part of it."
Favre could not be reached for comment. As Cook cracked, "He can't hear that phone on his tractor, anyway."
