Ann Arbor, Mich. ? Michigan coach Lloyd Carr will retire today after 13 seasons, ending an era marked by highs of winning a national championship and five Big Ten titles and lows of losing to Ohio State and Appalachian State.

Carr told the Associated Press of his decision Sunday by phone, saying he wouldn’t comment further until a morning news conference today at the school.

The 62-year-old coach informed his players and staff of his retirement Sunday during a team meeting at Schembechler Hall.

“It’s a hard thing to deal with,” safety Jamar Adams said. “We’re like a family, and when the head of your family is leaving, it’s hard.”
