Earlier this morning former Michigan Head Football Coach Bo Schembechler collapsed during a television taping at WXYZ television in Detroit.

Schembechler was taken by ambulance to Providence Hospital in the Detroit area. We have no report on his condition, but onlookers at the television station said that the situation appeared to be serious.

Schembechler is a native of Barberton, Ohio, and one of the architects of the Ohio State vs. Michigan rivalry. His 10-year competition with the late Woody Hayes is considered by many as the highpoint of the rivalry. Schembeckler played for Hayes at Miami of Ohio and later was a member of Hayes' OSU coaching staff.
More details when they are known.
