"On the day the Cavaliers welcomed back Daniel Gibson, they said goodbye to Mo Williams. Such is life on the injury carousel, which the Cavaliers just can't seem to jump off.

Williams received a cortisone shot in his ailing left hip Wednesday. He missed the game against the Phoenix Suns and said he'll be out ''a couple of weeks,'' although the team refused to put a timeline on it. Williams was walking with a slight limp before the game because of the cortisone shot.

''Just want to get the pain out of there,'' he said. ''That's the biggest thing.''

Ramon Sessions started in Williams' place and will likely remain there however long Williams is out. Sessions averaged 18 points and 7.5 assists in the last two games of the West Coast trip.

''Obviously it's a big loss,'' Cavs coach Byron Scott said. ''Mo's one of our leaders, one of our best scorers. He's been doing a real good job directing the team. I feel good about Sess being there. He's very capable of running our team. Even though it's a big loss, it gives us a chance to develop him even more.''

Williams said surgery is not an option at this point. He'll try to make it through the rest of the season, then spend part of his summer in Vancouver working with physiotherapist Alex McKechnie.

He previously worked with McKechnie a few years ago following hernia surgery and didn't have any real problems with his abdominal area until this year. Now it's time to go back. Williams said he'll spend about a week every month this summer in Vancouver working with McKechnie.

Powe update

Leon Powe returned to the court Wednesday for the first time following right knee surgery to repair a torn meniscus. He did some light shooting and no real running. Powe's initial timeline was four to six weeks before returning.

''I'm surprised at how good it felt,'' Powe said.

Eyenga is close

Christian Eyenga looked good during shoot-around Wednesday morning, Scott said, but he is staying cautious this time and keeping him out another couple of days. There is still some swelling in Eyenga's tender right ankle."
