The New York Knicks have signed Earl Barron.

The Knicks had a roster spot become available following the retirement of Rasheed Wallace.

Barron played for the Washington Wizards earlier this season and was waived in December.

Rasheed Wallace has again retired from the NBA after battling injury issues throughout this season, the New York Knicks announced on Wednesday.

“Rasheed has given this team everything he had,” Mike Woodson said in a statement. “He is a winner, true professional and leader on and off the court. Due to his injury, he will not be available to play for us during the playoffs."

When healthy, Wallace fortified the Knicks' defense and provided floor spacing, averaging four points and four rebounds in 21 games.

Wallace, 38, had not played for the past two seasons before coming out of retirement for the Knicks.

The New York Knicks announced on Tuesday that they signed Quentin Richardson for the rest of the season.

A 12-year NBA veteran, Richardson played four seasons with the Knicks from 2005 to 2009. He has career averages of 10.3 points and 4.7 rebounds.

Richardson had not played for an NBA team this season and will be eligible for the playoffs.

The Knicks were pursuing a wing player after releasing Solomon Jones on Monday.

The New York Knicks defeated the Indiana Pacers 90-80 on Sunday afternoon to clinch the No. 2 seed in the Eastern Conference.

The Pacers are currently third, two games ahead of the Brooklyn Nets.

The New York Knicks expect to have Tyson Chandler and Kenyon Martin back for the playoffs.

"They will be there, yes," coach Mike Woodson said.

There is a chance that Rasheed Wallace will return from injury as well.

Wallace has not played since Dec. 13 due to a stress fracture in his right foot.

Chandler has missed four consecutive games and 14 of the past 18 due to a bulging disk in his neck. Martin has missed the past three games with a sprained left ankle and five of the last six.

The New York Knicks will sign Solomon Jones for the remainder of the season, according to sources.

Jones received his letter of clearance from China on Friday to join the Knicks for the season and playoffs. Jones averaged 15.8 points and 10.4 rebounds this season with Liaoning of the Chinese Basketball Association.

Jones played parts of the 2011-12 season with the New Orleans Hornets and Los Angeles Clippers and played 58 games with the Atlanta Hawks in his first NBA season in 2006-07.

The Knicks plan to release Kurt Thomas to create room on the roster.

James Singleton had been reported as the player the Knicks were going to sign, but his deal apparently fell through.

Carmelo Anthony is hoping fans and the media will have patience with Derrick Rose as he continues his comeback from knee surgery.

"I wish y'all would stop rushing Derrick back," Anthony said. "Please. He shouldn't come back until he's about 110 percent ready. I don't think he should come back if he's not ready to go out there and play. If he can't compete at a high level, then what's a couple more months going to do? What's two more months going to do? I don't think he should come back, and that's just my opinion.

"I really don't know where he's at with his rehab and stuff like that, but I feel bad for him because I know he's got to deal with that every day, he's got to deal with that question. And nobody really knows on the outside what he's really going through, what his body is going through. So until he's 100 percent right, I would hope he would sit out."

The New York Knicks are close to signing James Singleton and will release Kurt Thomas to make room on the roster.

After averaging 8.2 points and 6.8 rebounds in 12 games for the Washington Wizards last season, Singleton spent the past year playing in China.

Thomas, 40, has missed the Knicks' past 12 games because of a stress fracture in his right foot, and he will have surgery next week.

New York Knicks forward Carmelo Anthony has the NBA's top selling jersey.

He moved past LeBron James and is the first member of the Knicks to top the list since the league began compiling it during the 2001-02 season.

The list is based on sales at the NBA Store in New York and on NBAStore.com since last November.

After Anthony and James, the top five was rounded out by Kevin Durant, Kobe Bryant and Derrick Rose.

According to Elias Sports, the 2012-13 NBA season is the first in which five different teams have enjoyed win streaks of at least twelve games.

The New York Knicks defeated the Oklahoma City Thunder on Sunday, extending their current run to 12 straight wins.

The Miami Heat, Denver Nuggets, Los Angeles Clippers and Thunder also had streaks of at least 12 wins this season.
