James Wisniewski was in the car with PGA Tour pro Bud Cauley when it crashed Friday night in Ohio.
The former NHL defenseman sustained "a couple broken ribs" in the crash and was still in hospital Sunday, Justin Thomas - the world's No. 1 golfer and a good friend of Cauley - said after completing his fourth round at the Memorial Tournament, according to Steve Gorten and Bill Rabinowitz of the Columbus Dispatch.
Cauley was in surgery after suffering a collapsed lung, five broken ribs, and a fractured left leg, as confirmed by his management firm IMG.
The accident was first reported by Golf Channel's Todd Lewis on Saturday night.
Wisniewski owns a home in Dublin, Ohio, where the Memorial Tournament was being held, and Thomas told the Dispatch that Cauley had been staying with the longtime blue-liner this week.
There were two other people in the car at the time of the accident.
Wisniewski played for six teams in 11 NHL seasons, spending parts of four with the Columbus Blue Jackets from 2011-15. He represented the United States at the Olympics in February.
