Two Pennsylvania men are admitting taking part in a rock-throwing incident that badly injured an Ohio teacher on Interstate 80 last year.

Union County Judge Michael Sholley said during a hearing Tuesday that he'll announce whether he's accepting the plea deals at sentencing for defendants Keefer McGee and Dylan Lahr.

McGee's plea to aggravated assault could send him to the county jail for nearly a year. Lahr could serve more than four years under a plea to trespassing, agricultural vandalism and two counts of aggravated assault.

A third man, Tyler Porter, is considering a plea offer.

The fourth defendant, Lahr's brother Brett Lahr, awaits a sentencing hearing later Tuesday after pleading no contest to a conspiracy count.

The attack left Sharon Budd of Uniontown, Ohio, with severe head injuries.
