Kenyon Martin didn’t join his teammates in shooting practice Wednesday because of an apparent new wrist injury.

Tuesday night in the visitor’s locker room in Indianapolis, Martin sported either a black soft cast or wrap on his right wrist. Martin, who also has the flu, was nowhere to be found in the gym.

According to a league source, Martin’s protective wrist wear is “precautionary’’ and his sore wrist isn’t considered extensive.

The Knicks didn’t list Martin on the injury report before Thursday night’s Game 5. He had a poor Game 4 and has had a mediocre series against the Pacers, not imposing his will against the burly Pacers as hoped. Thrust into the starting lineup at power forward Tuesday, Martin was scoreless (0-for-3) with five rebounds — none on the offensive glass — in 28:54.

The addition of Amar’e Stoudemire to the rotation could have affected Martin. Stoudemire isn’t a good rebounder and the two haven’t made a good rebounding tandem. Stoudemire, in his second game back, played just 11:17, scored four points, hauled in four rebounds but also committed four fouls and a technical.

Asked if he will stick with the rusty Stoudemire, coach Mike Woodson said, “Stat, he’s only playing 10-12 minutes. He’s played in two games. His minutes have been pretty positive. I just thought last night we got into a shoving war in terms of unnecessary fouls. It was just ridiculous. That’s what put us behind in the second quarter. The shoving, pushing, technicals. Those things have got to be eliminated.’’
