Kyrie Irving felt a pop in his left knee after injuring it in the third quarter of the Cleveland Cavaliers' 91-76 loss to the Indiana Pacers on Tuesday.

Irving felt weak following his return to the game, despite being helped to the locker room without putting pressure on his left leg.

"I thought the worst had happened," Irving said. "My left knee is pretty weak right now. I was falling all over the place. I didn't have my legs under me."

Irving missed 38 games over the past two seasons. A long-term injury to Irving could change the direction of the Cavaliers.

Brad Stevens said on Monday that the Boston Celtics are leaving open the possibility of giving Rajon Rondo an opportunity to get into basketball shape and continue his rehabilitation in the NBA D-League.

Rondo has not played since Jan. 25 after suffering a torn ACL and is expected to return this season.

"I would make that a decision on him and our staff," Stevens said. "That is something that has been discussed, probably some positives and negatives to that, but at the end of the day, it is an option as part of his rehabilitation."

The Maine Red Claws are the Celtics' D-League affiliate.

Rondo likely wouldn't return to the Celtics during their five-game West Coast road trip beginning on Jan. 5, but Stevens said he could spent time with Maine practicing and playing in D-League games before coming back to the NBA.

Xavier Henry will be sidelined due to a bone bruise in his right knee and an abnormality of the lateral meniscus, the Los Angeles Lakers announced Monday.

Henry will be re-evaluated in seven to 10 days.

Henry is averaging 10.4 points this season.

C.J. McCollum has missed the entire season to date with a broken bone in his foot.

McCollum was the 10th overall pick in the 2013 NBA Draft by the Portland Trail Blazers.

McCollum is expected to make his NBA debut shortly after New Year's Day, according to a source.

Xavier Henry suffered a strain in his right knee on Sunday night and will undergo an MRI on Monday to determine the significance of the injury.

Henry is averaging 10.4 points and 2.8 rebounds this season.

Henry made the Los Angeles Lakers' roster out of training camp.

The Lakers are without Steve Nash, Steve Blake and Kobe Bryant in the backcourt.

Steve Nash went through light shooting drills on Sunday.

Nash is still two to three weeks away from receiving re-evaluation.

Nash has missed most of the Los Angeles Lakers' season due to a nerve issue in his leg.

Brook Lopez will undergo surgery on his injured right foot on Jan. 4.

This will be the third surgery on the same foot of Lopez.

Lopez originally fractured the bone in December 2011.

Devin Harris plans to participate in his first full practice of the season during the second week of January.

Harris has yet to play after undergoing surgery on a toe on his left foot this past summer.

“Pain is my guide,” Harris said. “And there’s no pain right now.

“I’m confident that we’ve figured out the problem, but we just want to test it when it’s right. It’s more important to be 100 percent right than anything else.”

Andrew Bynum has mentioned he is unsure of how much longer he wants to play because of lingering pain in his knees.

But Bynum has been highly engaged in workouts and rehab after signing with the Cleveland Cavaliers.

Bynum lost more than 25 pounds and worked hard on improving his stamina.

Derrick Rose could become a fixture on the Chicago Bulls' bench by mid-January.

Rose has already started the rehab process.

“Well, he can lift upper-body, do all his rehab stuff, so he is starting to move around a little bit now,’’ Thibodeau said. “He can go in the pool.’

Rose is not expected to return to game action until the 2014 preseason.
