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.

The New Orleans Pelicans have waived forward Lou Amundson.

Amundson appeared in 18 games for the Pelicans this season and averaged 2.1 points, 3.1 rebounds and 0.6 blocks in 10.2 minutes per game.

The San Antonio Spurs have recalled guard Nando De Colo and forward Malcolm Thomas from the Austin Toros of the NBA Development League.

Both players made their fourth appearance for the Toros this season on Sunday when they led Austin to a 96-93 home victory over the Tulsa 66ers.

The NBA acknowledged the officiating crew should have called a foul on Shawn Marion to put Kevin Love at the free throw line near the end of regulation in the Dallas Mavericks' 100-98 win over the Minnesota Timberwolves.

Marion swiped down and appeared to foul Love, who was attempting a game-tying jumper from the left baseline.

“Through postgame video review, we have determined that Minnesota’s Kevin Love was fouled on the right arm by Dallas’ Shawn Marion while attempting a two-point field goal," Rod Thorn said. "Love should have been awarded two free throws with one second left on the clock.”

Eric Bledsoe has had a breakout season with the Phoenix Suns, receiving increased playing time and general usage.

Bledsoe will be a restricted free agent in the offseason.

"We'll have no problem stepping up and paying Eric whatever it takes to keep him," said Ryan McDonough.

"We feel like we're holding the cards with Eric, and more importantly, I think Eric's had a good experience here so far."

The New York Knicks have signed forward Jeremy Tyler of the Erie BayHawks, and waived guard Chris Smith.

Tyler, 6-10, 250-pounds, has averaged 18.0 points, on 47.8-percent shooting, and 10.2 rebounds over 31.0 minutes in six games (all starts) with the BayHawks. He originally signed with New York on Aug. 6, after playing for the Knicks’ entry in NBA Summer League in Las Vegas, NV, and was waived on Oct. 25 while recovering from a broken right fifth metatarsal. 

Smith, 6-0, 200-pounds, signed with New York on Sep. 10, and appeared in two games, playing two minutes. He was assigned to Erie on Nov. 18, where he played six games before being recalled on Dec. 17.

The Cleveland Cavaliers and Chicago Bulls are discussing a trade-and-waive deal of Andrew Bynum for Luol Deng.

The Bulls would save in excess of $20 million in salary and taxes by trading Deng while waiving Bynum.

The Bulls maintain that they believe they will be able to re-sign Deng in the offseason.

The Los Angeles Lakers and Cleveland Cavaliers have discussed a trade involving a swap of Pau Gasol for Andrew Bynum.

No deal is believed to be imminent, but both sides are considering it ahead of the Jan. 7 deadline for when the second half of Bynum's salary for the season becomes guaranteed.

The Lakers could save more than $20 million in salary and luxury taxes by trading for Bynum and then waiving him.

A trade would need to include at least one additional player to make the deal work and perhaps other assets from the Cavaliers.

Sources say the Lakers are reluctant to part with Gasol in any trade without receiving assets of some value in return.

The Cavaliers have pursued Gasol since this past summer when they had extensive talks with the Lakers, which ended after Dwight Howard signed with the Houston Rockets.

The Golden State Warriors have recalled center Ognjen Kuzmic from the Santa Cruz Warriors of the NBA Development League.

Kuzmic was assigned to Santa Cruz on Dec. 28 and played 16 minutes in Sunday's game against the Bakersfield Jam, registering two points, nine rebounds and one blocked shot.

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.
