KANSAS CITY, Mo. -- Chiefs star Priest Holmes had hip surgery and is expected to be running at full speed in June.

Holmes, the NFL's offensive player of the year, underwent arthroscopic surgery in Miami on Tuesday. The 29-year-old running back missed the last two games of the season.

Coach Dick Vermeil, speaking Wednesday from the NFL meetings in Phoenix, said Holmes will be on crutches for about four weeks and miss minicamp.

"But I am told he'll be able to run full speed by June, and that's what we're counting on,'' he said.

Holmes was having one of the best seasons by a running back when he was injured after being caught from behind in a game at Denver in December. Still, he finished with 1,615 rushing yards and 24 touchdowns.

While questions linger about Holmes' health, the Chiefs have decided to hold off on his demand to renegotiate his contract. General manager Carl Peterson has indicated he might be willing to discuss an extension.

The Chiefs sent Holmes to a specialist before the operation. Vermeil said Holmes had a fourth MRI and it was decided this procedure would hasten the healing process.

Vermeil said team doctor Jon Browne and trainer Dave Kendall were in Miami for the surgery.

"I spoke with him before the surgery and he was feeling very positive because he felt this was going to help speed his recovery,'' Vermeil said. "After the surgery, he told Dave Kendall that he felt good.''
