Archer, 49, who joined the Steelers staff in March 1996, has spent seven seasons as the team's linebackers coach. Archer returns to Kentucky, where he served as defensive coordinator/assistant head coach and linebackers coach from 1993-1995.
"I have really enjoyed my seven years with the Steelers organization," Archer said. "This was always a team I dreamed of working or playing for, and I fulfilled those dreams.
"I want to thank the Rooney family and Coach Cowher for the opportunity." added Archer. "The Kentucky position and the fact I will be there with my two children, both of whom will be attending the university, is a big plus as my family is very important to me. I look forward to the challenge of college football again and wish the Steelers organization the best of luck in its drive to win the Super Bowl in 2003."
"Mike has made a valuable contribution to our success over the past seven seasons" said Head Coach Bill Cowher. "This is an excellent career opportunity for Mike, and we wish he and his family all the best."
