The Oklahoma City Thunder have reassigned Perry Jones, Jeremy Lamb and DeAndre Liggins to the Tulsa 66ers, the Thunders’ NBA Development League affiliate.

Jones (6-11, 235, Baylor) has appeared in 29 games for Oklahoma City this season, averaging 1.9 points, 1.4 rebounds and 7.0 minutes. In his previous stints with Tulsa, Jones averaged 14.1 points, 7.0 rebounds and 33.0 minutes in 11 games.

Lamb (6-5, 180, Connecticut) has played in 18 games for the Thunder this season, averaging 2.2 points and 4.4 minutes. In his previous assignments to the 66ers, he averaged 21.1 points, 5.5 rebounds, 3.4 assists and 33.2 minutes in 14 games.

Derek Fisher signed with the Oklahoma City Thunder this week a few months after leaving the Dallas Mavericks citing an injured knee and desire to be with his family in California.

“He and Mark (Cuban) had an agreement when he came here that he would come and if things got to where he needed to leave for family reasons, he would do that,” Rick Carlisle said. “That’s what he said was the situation. I’m going to take him at his word.

“Look, he’s one of those guys who have been around this league for a long time. He’s won a lot of rings. My opinion is he’s earned the right to do what’s best for him.

“If Oklahoma City’s a good situation for him, then that’s what he should do. We’ve got to carry on. We can’t be concerned about things like that.”

A league source told Jeff Caplan of NBA.com that the Mavericks' front office was "agitated" by Fisher's decision.

The Oklahoma City Thunder has signed guard Derek Fisher for the remainder of the season.

“We are excited to welcome Derek back to the Thunder organization," Sam Presti said in a statement. "He contributed to our team in various ways last season, and we are looking forward to him joining us again.”

Fisher played nine games this season with the Dallas Mavericks before asking for his release in December because he wanted to return to his family.

Fisher, 38, ended last season with a run to the NBA Finals with the Thunder.

Kevin Martin has played well with the Oklahoma City Thunder’s second unit, and already has developed chemistry with Nick Collison.

Collison has registered 78 assists this season, 42 of which have gone to Martin.

“Him and (James) Harden had a great two-man game, and me and Brad Miller, we had a great two-man game,” Martin explained. “So it's kind of like me and Brad divorced, him and Harden divorced and me and Nick got together — in a basketball way.”

Collison and Martin have been so effective working the two-man game that Collison leads the Thunder with a 7.9 assist-to-turnover ratio, according to 82games.com.

“His basketball IQ is very high, so he knows when to do something and when not to do something,” Martin said. “He doesn't force anything. He's just a high IQ basketball player.”
