Ann Arbor, MI (Sports Network) - Former Michigan head football coach and current associate athletic director Lloyd Carr will retire from the school's athletic department in September.

Carr will officially retire September 1, ending 30 years of service to the university.

"I am thankful for the wonderful opportunity to assist two great coaches here in Bo Schembechler and Gary Moeller and I will always appreciate Joe Roberson's decision to name me the head coach in 1995," said Carr. "I am also appreciative for those I worked with and for all the great friendships I have developed.

"Most of all, I am thankful for the young men I coached and for all the memories I have from my time at Michigan."

Carr spent 13 years as the Wolverines' head football coach, compiling an overall record of 122-40 with one national championship (1997) and five Big Ten titles. Only the legendary Schembechler and Fielding H. Yost won more games than Carr.

Carr joined Michigan in 1980 as defensive backs coach under Schembechler, serving in that role until 1986. He became defensive coordinator in 1987 and continued to hold that position when Schembechler was replaced by Gary Moeller in 1990. Carr then took over for Moeller in 1995 and retired from his coaching duties after the 2007 season.
