A former Michigan State University gymnastics coach was convicted on Friday of lying to investigators when she told them she did not remember if two teenagers told her that they had been sexually abused by Lawrence G. Nassar, a former team doctor for the university and U.S.A. Gymnastics, who sexually abused numerous girls and young women.

A jury found the coach, Kathie Klages, guilty of two counts of lying to a peace officer. She will face a maximum prison term of four years and a fine of up to $10,000 when she is sentenced on April 15, according to prosecutors.

Ms. Klages had told investigators that she was not aware of Dr. Nassar’s abuse before 2016, but prosecutors argued that she knew of the abuse for more than 20 years.

During a four-day jury trial, in Ingham County Circuit Court, two women testified that they told Ms. Klages about Dr. Nassar’s abuse in 1997, according to Mary Chartier, Ms. Klages’s lawyer. Ms. Klages testified that when she was interviewed about the conversation 21 years later, she did not remember it, Ms. Chartier said.
