ANN ARBOR, Mich. (AP) - Michigan offensive lineman Graham Glasgow has pleaded guilty to a charge of operating a vehicle while visibly impaired. Glasgow appeared Monday in front of 15th District Court Judge Joseph Burke, who set sentencing for July 14. The misdemeanor carries a penalty of up to 93 days in jail. As part of the plea deal, the government amended the charge from operating while intoxicated to operating while visibly impaired. Monday's plea stems from a March 15 incident. Glasgow did not comment on the case while leaving the courtroom. Michigan coach Brady Hoke suspended Glasgow for part of spring practice and the season-opening game against Appalachian State. As a sophomore last season, Glasgow made nine starts at center and four at left guard.
