The Pittsburgh Steelers won't bring back a trio of coaches under Mike Tomlin.

Randy Fichtner, the team's offensive coordinator, won't return. Pittsburgh won't renew the contracts of offensive line coach Shaun Sarrett and defensive backs coach Tom Bradley either.

James Daniel, who's been with the organization since 2004, also is retiring as tight ends coach after 17 seasons with the organization.

"I want to thank all three of the coaches for their commitment and dedication to the Pittsburgh Steelers," Tomlin said in a statement. "They have all played integral roles in our success and I am appreciative of their efforts. Personally, Randy and I have been in Pittsburgh since I hired him in 2007, but our relationship began well before that. He has been a friend of mine for years and wish his family nothing but the best, and I am eternally grateful for our relationship both on and off the field."
