Jose Calderon has been diagnosed with a left Achilles strain, the New York Knicks announced Saturday. 

Calderon underwent an MRI.

He will not dress for Saturday's home game versus Toronto.

Russell Westbrook underwent a surgical procedure on a fracture to his zygomatic arch bone. 

Westbrook will miss Sunday's game and will be reevaluated this week.

Westbrook suffered the injury in the Oklahoma City Thunder's loss to the Portland Trail Blazers on Friday.

Derrick Rose appeared at the Chicago Bulls' practice facility on Saturday.

Rose was in good spirits and will begin his rehabilitation process.

Rose did not address the media but is very confident he will play again this season. The Bulls believe he will miss four to six weeks with the torn meniscus in his knee.

Joel Embiid appears to now be in much better shape than he was in five weeks ago when a report indicated he weighed close to 300 pounds.

Embiid was working out before the Philadelphia 76ers' game on Friday and he was moving well, executing jump hooks with either hand and exhibiting good mobility.

Embiid has missed the entire season with a right foot stress fracture.

LeBron James will miss Friday's game against the Indiana Pacers due to rest.

David Blatt said he made the decision to sit James based on “a combination of things” and not one specific ailment.

“It was not his idea, it was mine. Let’s put it that way,” Blatt said. “We have our hand on the pulse of LeBron and all our players. We’re doing what we have to do here to keep our team healthy all the way through the season.”

The Cleveland Cavaliers are 2-8 this season in games without James.

Derrick Rose is expected to return from his knee surgery in four to six weeks.

"We expect Derrick to be playing this season," said Gar Forman.

Rose had the damaged part of his meniscus removed during the surgery, which was described as minor.

Rose first tore the meniscus in his right knee in November of 2013 and subsequently missed the remainder of the 13-14 season.

Kyrie Irving experienced a left shoulder injury during Thursday's game against the Golden State Warriors. 

Irving will not travel with the team tonight to Indianapolis and will receive additional examination, including an MRI, on Friday morning, the Cleveland Cavaliers announced.

He is listed as doubtful for the Cavaliers game against the Pacers Friday night and his status will be updated as appropriate.

Danny Ainge revealed Thursday that Jared Sullinger did not meet any of the Boston Celtics' team-wide conditioning goals this season.

Sullinger is out for the remainder of the season with a foot injury.

“Well, Jared and I have talked a lot about (his conditioning) over the past year,” Ainge said on 98.5 The Sports Hub’s “Toucher & Rich." “It’s something we take great pride in with our players. Our players have really bought in to our program, and a lot of guys — I think every guy has met the goals that they have set in regards to strength and conditioning, and body fat, and weight, and all the different things our strength coaches do on a regular basis.

“Jared just hasn’t met his goals. He’s not up to the standards that he wants and is not up to the standards that we think are in his best interests for the long-term health of his career. He’s not up to par to the standards that we feel are necessary to be a consistent winning player and play with great conditioning.”

Paul George participated in his first full practice this season with the Indiana Pacers on Thursday, beating his personal goal of March 1 by several days.

"Felt good. Felt really good," George said, "to be able to go through a full practice now and go up and down, it's a big step for me."

George does not yet have a firm date for his return from a right leg injury.

"I'm still hopeful," George said. "That's the date that I wish to return. (But) long ways away, still got some steps and some hurdles to overcome. That's still a goal of mine."

Frank Vogel said Thursday was the next step in the process for George.

"We want him to come back when he's ready to come back. He's eager to get out on the court, but he's not going to do it before he's ready," Vogel said. "We understand once he's medically cleared to play in a game, then there's going to be: Is he ready to play in a game? And that could be a few more weeks beyond that. It's really going to be something we monitor almost on a daily basis and hopefully it progresses as well."

Darren Collison will have surgery on Tuesday to repair a core muscle injury that will likely end his season.

Collison suffered a strained hip flexor on Feb. 5 and hasn't played since.

Collison will be re-evaluated three to six weeks after the surgery and there is no timetable for his return.

The Sacramento Kings signed Collison in the offseason.
