Sacramento Kings rookie DeMarcus Cousins got into an altercation with teammate Donte Greene after Cousins didn't get the ball on the final possession of a 99-97 loss to Oklahoma City Saturday night, two league sources said, with one source adding that Cousins was not allowed to join the team for its flight to Phoenix for a game Sunday night.

Kings coach Paul Westphal, reached by telephone shortly before the team departed for Phoenix, said, "I'm about to get on this plane and I really can't talk about this right now."

When asked if Cousins would be aboard the flight, Westphal said, "I've got to go. Sorry."

Kings general manager Geoff Petrie was not with the team and will probably need to hear more details before he makes a final decision on Cousins' punishment, a source said.

It's the latest incident in what has been a rocky rookie season for Cousins, who has already been fined by the team for a verbal confrontation with a training staff member and also was tossed out of a practice after talking back to Westphal.

If Cousins does not play Sunday it would be the first time Cousins missed a game for his behavior.

Cousins became upset after he didn't touch the ball on the last play, which resulted in a missed 3-pointer by Tyreke Evans.

According to the Sacramento Bee's Kings blog, "Westphal said the final play wasn't drawn up specifically for Evans and that Donte Greene had options inbounding the ball. Evans became the best option because he was open and the Thunder took away DeMarcus Cousins in the post."

One source said Cousins and Green argued in the locker room, with Cousins telling everyone he wanted respect, regardless of his rookie status.

Cousins is averaging 13.9 points and 8.0 rebounds per game.
