A 20-year-old Southern Oregon University student who suffered serious head injuries in a rollover crash last weekend is recovering, hospital officials said.

Irah Nishi was in good condition at Rogue Valley Medical Center Tuesday, hospital spokesman Grant Walker said.

Nishi was the driver of a Toyota Tercel that rolled over at about 1:45 a.m. Sunday on Tolman Creek Road between East Main Street and Abbott Avenue, Ashland police said. Nishi wasn't wearing a seat belt and was thrown from the car, Ashland Deputy Police Chief Rich Walsh said.

Passenger Benjamin Rosenberg, a fellow 20-year-old SOU student, was wearing a seat belt and suffered only a minor leg injury that didn't require immediate medical treatment, police said.

The investigation into the crash is ongoing, Walsh said. Officer Steve MacLennan was handling the case, but was injured in a crash Monday while patrolling on his motorcycle. The Tolman Creek Road crash has been assigned to other officers while MacLennan recovers from cuts, scrapes and a broken arm.
