Matt Schembechler, the son of former Michigan head coach Bo Schembechler, alleged that he was sexually abused by late team doctor Robert Anderson. A news conference was held on Thursday afternoon.

During that news conference, Matt Schembechler says he was assaulted in 1969, when he was 10 years old. He claimed that Anderson “groped his testicles and penetrated him from behind,” according to MLive.com.

“It is a deeply personal story of abuse and betrayal, a story of mistrust in a doctor and betrayal of my father,” Matt Schembechler said.

Matt Schembechler says he told his mother what happened after the incident occurred and he was instructed to tell Bo Schembechler about what happened. He says that telling his father did not go well.

“I tried to tell him repeatedly, but my efforts earned me a punch in the chest,” Matt Schembechler said. “It was the beginning of the end of our relationship.”

Two former Michigan football players — offensive tackle Daniel Kwiatowski and wide receiver Gilvanni Johnson — joined Schembechler at the news conference on Thursday. Both claimed that they were also sexually abused by Anderson during physical examinations.

The University of Michigan released a statement on Thursday saying it sympathizes with the victims.

“We thank them for their bravery in coming forward,” the statement says. “We condemn and apologize for the tragic misconduct of the late Dr. Robert Anderson, who left the University 17 years ago and died 13 years ago.

“We are committed to resolving their claims and to continuing the court-guided confidential mediation process.”
