LINCOLN, Neb. (AP) — The Nebraska attorney general’s office is seeking disciplinary action against a Lincoln orthopedic surgeon and former Husker football player who is accused of practicing medicine while impaired.

The petition filed this week alleges that Dr. Scott E. Strasburger arrived at work on Nov. 26 in an impaired state that prevented him from performing surgeries.

According to the petition, Strasburger refused to submit to a drug test. The petition says Strasburger failed a drug test in July, months after completing an outpatient treatment program. It says Strasburger initially tested positive for a controlled substance in October 2013.

A phone message left at Strasburger’s office wasn’t immediately returned. A home phone number rang unanswered.

Strasburger was a defensive end for the Huskers and was drafted by the Dallas Cowboys in 1985.
