Ryan Clark, who played safety in the NFL for 13 seasons, announced Wednesday that he’s retiring.

Clark, 35, made the announcement on ESPN’s “NFL Live,” saying he will retire as a Pittsburgh Steeler. Clark reportedly will step into a role with ESPN.

He spent eight seasons as a Steeler, rejoining the Washington Redskins last year when the Steelers opted to let him go in free agency.

He began his career with the New York Giants as an undrafted player out of LSU in 2002. He signed with Washington in 2004 and played two seasons there before joining Pittsburgh in 2006 and starting 109 games for the Steelers.

Clark finished his career with 929 tackles and 16 interceptions. He topped 100 tackles in each of his final four seasons.

Clark played despite having sickle cell trait — a genetic condition that can affect red blood cells. The high elevation in Denver forced him from a game in October 2007, and he ended up needing his spleen and gall bladder removed.

He never played in Denver again, sitting out a playoff game in January 2012 and the 2012 season opener.
