Pittsburgh, PA (My Sportsbook) - The Pittsburgh Steelers released standout linebacker Joey Porter along with running back Verron Haynes on Thursday, just hours before the free agency period was set to begin.

Porter has played each of his eight professional seasons in Pittsburgh after being selected by the Steelers in the third round (73rd overall) of the 1999 NFL Draft out of Colorado State.

He has appeared in 122 out of a possible 128 games, racking up 498 tackles, 60 sacks and 10 interceptions over that span. His sack total ranks fourth in team history.

Porter started in 14 games in 2006, and led the Steelers with seven quarterback sacks and also intercepted two passes, which tied for second on the team.

The 6-3, 250-pounder has earned three trips to the Pro Bowl and helped the Steelers to a Super Bowl Championship following the 2005 season.

Haynes was the Steelers' fifth-round draft choice in 2002 (166th overall). He played in 60 games with the Steelers and rushed for 738 yards and three touchdowns on 174 carries.

The Steelers also made tender offers to offensive tackle Max Starks and quarterback Brian St. Pierre, and released offensive tackle Ulish Booker.
