Marvin Williams will undergo surgery to repair his sore right heel/Achilles tendon.

Williams is expected to need approximately six months to recover.

Williams has a player option on his contract for the 13-14 season, which he is now certain to exercise.

Danilo Gallinari was scheduled for surgery to repair a torn anterior cruciate ligament, but that procedure has been delayed two weeks because of a setback in his rehab from a torn meniscus.

Gallinari underwent surgery on his meniscus four weeks ago

Gallinari might not return until later in January or maybe even February.

Portland Trail Blazers guard Wesley Matthews underwent a successful arthroscopic debridement of his left elbow on Wednesday.
 
Matthews’ recovery time is expected to be 3-4 weeks.
 
In his fourth NBA season and third with the Trail Blazers this season, Matthews averaged 14.8 points, 2.8 rebounds, a career-best 2.5 assists, a team-high 1.30 steals and 34.8 minutes in 69 games (all starts).

The Chicago Bulls and Derrick Rose have yet to determine whether Rose will participate in any pickup games with fellow NBA players in the offseason, when the former NBA MVP spends his time in California.

"We are in the process of sitting down and meeting with Derrick and his representatives and mapping out his offseason," John Paxson said on Sunday. "... We're going to map it all out and make sure everyone is on the same page.

"Whatever he's going to in terms of playing, that's to be determined. But the biggest thing is that he feels the knee is strong and safe and all the things that make him comfortable. I think every day that goes by, he feels better about it and that's all we're concerned about."

Paxson has been most impressed with how strong Rose has gotten and believes the added strength has improved Rose's outside shooting.

"We're fortunate that we've got a kid who is still young and is dedicated to the job and wants to continue being a great player," Paxson said. "I think he's going to come back bigger, stronger, better than ever."

Rose sat out the entire season after tearing his ACL in April, 2012.

After playing a second consecutive season with a torn ligament in his left wrist, Luol Deng doesn’t plan to have any procedure to repair the wrist, a league source told RealGM.

Deng made his second straight All-Star team this season for the Chicago Bulls, averaging 16.5 points, 6.3 rebounds and three assists in 75 games. He decided to bypass surgery after last summer’s Olympics and played all season with his wrist taped.

Instead of undergoing surgery, Deng will rest his wrist. He also dealt with a fractured thumb earlier in the season.

Deng led the Bulls to a 3-1 series lead over the Brooklyn Nets in the first round, but he missed the final seven games – including the series win – of Chicago’s playoff run due to lingering symptoms from a spinal tap. He’s since recovered and felt better. The Bulls’ season ended in a Game 5 series loss to the Miami Heat on May 15.

Over the past two seasons, Deng has cemented himself as an integral, durable forward on the Bulls, establishing himself under Tom Thibodeau as one of the NBA’s elite wing defenders.

Tony Parker underwent a precautionary MRI on his bruised left calf Thursday, and the San Antonio Spurs' guard received a positive outcome.

Parker said Thursday that his calf contusion is dissipating well.

Parker is averaging 18 points in five games since the injury, alternating two strong shooting performances (9 for 16 and 9 for 14) around three poor ones (6 for 17, 3 for 16, 6 for 20).

The Spurs lead the Memphis Grizzlies, 2-0, in the Western Conference Finals.

Dwyane Wade acknowledged before Wednesday's Game 1 against the Indiana Pacers that his left knee injury is more painful than it was last season.

This season's injury is a bone bruise while last year's involved the cartilage, which required surgery in the offseason.

"It’s unfortunate I’ve had to deal with this thing for two months now," Wade said. "When I feel great, I’m going to attack. When I don’t, I know how to be a team player and give of myself for other guys.

"Even though my knee isn’t 100 percent, it ain’t gone.”

Carmelo Anthony has a partially torn labrum in his left shoulder.

Anthony may need surgery to repair the injury, which he played 12 playoff games with.

The New York Knicks are hopeful that Anthony can avoid surgery with rest over the next three to four weeks.

Anthony originally injured his shoulder on April 14th and re-injured it in Game 5 of the first round against the Boston Celtics.

Anthony would likely need three to four months of recovery if he undergoes surgery.

Carmelo Anthony will have his injured left shoulder re-examined in order to determine how to treat it moving forward.

The New York Knicks are hopeful that Anthony will not need surgery and that it will improve with rest.

Anthony originally injured his shoulder during an April 14th win over the Indiana Pacers. Anthony reported that his left arm "popped in and out" when Kevin Garnett yanked his arm in Game 5 against the Boston Celtics.

Anthony had fluid drained from his right knee two months ago but according to the team official Anthony's knee has improved and won't need arthroscopic surgery. 

George Hill has been cleared to play and will start for the Indiana Pacers in Game 6 against the New York Knicks on Saturday night.

Pacers coach Frank Vogel said he doesn't expect Hill, who suffered a concussion on Tuesday night and missed Thursday's Game 5, to be limited.

The team released the following statement about 90 minutes prior to the tip:

Over the last two days under the care of the Indiana Pacers' medical staff, George Hill has participated in each step of the NBA's Return-to-Participation Exertion Protocol as part of the NBA's Concussion Policy.  

During the process, George remained symptom-free after each step including his workouts earlier today. After consultation with Dr. Jeffrey Kutcher, the NBA's Director of Concussion Management, the Pacers' team physicians have cleared George to play in tonight's game.
