Dallas Clark is retiring from the NFL after 11 seasons. He'll make it official at a Wednesday news conference with the Indianapolis Colts, the team he spent nine years with while establishing himself as one of the game's best tight ends. Paired with Peyton Manning, Clark set franchise records for career receptions and receiving touchdowns by a tight end. Clark and Manning both left the team following the 2011 season, and the tight end's numbers dipped without the QB great. He posted 47 catches for 435 yards (four TDs) in 2012 with the Bucs and 31 grabs for 343 yards (three TDs) with the Ravens last season.
