GREEN BAY, Wis. � The Green Bay Packers placed Brett Favre on the NFL's reserve-retired list, meaning he no longer counts on the team's 80-player roster.

General manager Ted Thompson says the move is procedural in advance of the NFL draft. The 38-year-old Favre announced his retirement March 6 in an emotional news conference. The team has announced it will retire the three-time MVP's No. 4 when the season starts in September.

Thompson also says the team has waived three offensive linemen � Tony Palmer, Chris Patrick and Cliff Washburn � to reduce the active roster to 68 players.

Palmer played in a pair of games in 2007 before sustaining a season-ending neck injury. Patrick and Washburn were on the team's practice squad before signing contracts for 2008.
