FRISCO, Texas -- Dallas Cowboys running back Ezekiel Elliott missed his second straight day of organized team activities after being in a car accident Sunday.

The Cowboys said Elliott suffered a hit to the head in the "minor accident" and is being evaluated. Elliott is doing conditioning work off to the side, the team said.

Garrett said the team learned of Elliott's accident on Monday morning. He said the running back was coming back from a charity event Sunday night when the car in which he was riding was involved in the accident.

"When he came in on Monday he had some body stiffness and some neck stiffness, so we got him checked out," Garrett said. "We felt like it was the right thing to do to keep him out. He's done the dynamic warm-up over the last couple of days, but we kept him out of the practice portion of it."

Elliott, who led the NFL with 1,631 yards in 2016, will not practice Thursday, but Garrett said he expects his star running back to practice when the OTAs resume next Tuesday.

Running backs coach Gary Brown and offensive coordinator Scott Linehan said Elliott appears fine. During the early portion of practice, Elliott ran along the sidelines and returned to watch the final portion of 11-on-11 drills.

"He's fine," running backs coach Gary Brown said. "He's good. Everything's good."

The week before the Cowboys' playoff game against the Green Bay Packers in January, Elliott was involved in a minor accident on his way to the facility.

With Elliott not practicing, Darren McFadden took the first-team snaps.

Elliott's representatives declined comment.

The Cowboys opened up Phase 3 of their offseason program Monday and had their first 11-on-11 work Tuesday. The Cowboys hold their OTAs on Tuesday, Wednesday and Thursday for three weeks. The offseason concludes with a mandatory minicamp in June.
