MADRAS, Ore. (AP) — The daughter-in-law of Nike co-founder Bill Bowerman  has pleaded guilty to sexual abuse for having a relationship with a 17-year-old boy on the track team she coached in central Oregon.

The Bulletin reports that 45-year-old Melissa Bowerman was sentenced Monday to five years of probation.

During probation, her internet usage will be restricted and she's not allowed to contact males under age 18, except family members. A violation could land Bowerman in prison for up to 1 ½ years.

She will also have to register as a sex offender.

Bowerman did not make a statement at the hearing. Her attorney, Stephen Houze, says therapy has been "very valuable" for Bowerman. He says she had a previously undiagnosed mental health condition.

The former Madras High coach spent 26 days in jail after her July 2014 arrest.
