Adam Schefter of NFL Network lays out the procedure that quarterback Brett Favre would follow if/when he decides to play football again.

Favre currently is on the reserve/retired list.  To be activated from it, Favre only has to send written notice to the Packers and to the league of his desire to play.  The Packers would then have 24 hours to reinstate Favre, or to release him.

The other possibility would be to activate Favre and then attempt to trade him, if the Packers don’t want him back on the team.  But they would be required to use a roster spot on him until he is traded.

As to whether the Packers want Favre, Schefter reports that there are folks in the organization who go both ways on the issue.

As to whether Favre wants to play, Schefter confirms that Favre is training as if he’s returning.

If he chooses to do so, the Packers have limited options — and there’s a good chance that they like none of them.
