In a statement released by the team, Carlson said that after ''much thought and consideration,'' he and his wife Danielle decided this was the best decision.
The 6-foot-5, 248-pound Carlson played seven NFL seasons with Seattle, Minnesota and Arizona. He had a history of concussions before signing with the Cardinals last offseason.
With Arizona, Carlson played in 16 games, 12 as a starter, catching 33 passes for 350 yards and a touchdown. A second-round draft pick by the Seahawks out of Notre Dame in 2008, Carlson played in 90 games, with 210 catches for 2,256 yards and 15 touchdowns.
