The $100 million man will be the 30-minute man the rest of the season.

Amar’e Stoudemire has truly joined the 30-30 club. He turned 30 in November, and coach Mike Woodson said yesterday he won’t be permitted to play him more than 30 minutes the rest of the season because of Stoudemire’s recent left-knee surgery.

A combination of the medical staff led by Dr. Lisa Callahan, general manager Glen Grunwald and Woodson jointly agreed 30 minutes per game are enough for 2012-13 — for Stoudemire’s longevity and efficiency.

Woodson’s revelation that the restriction is season-long comes the day after Stoudemire was a near perfect 9-of-10 for a season-high 22 points in 22 minutes in a win over the 76ers. It also comes four days after the trade deadline when assuredly Stoudemire was available, with his maximum contract still having two years and $45 million left on it.

That the 30-minute cap will be in place the rest of the season also helps explain why the Knicks went after free agent Kenyon Martin. And it helps explain why Stoudemire has yet to voice complaints about not starting — or finishing — games. He has averaged 22.8 minutes this season off the bench, with a healthy 13.7 scoring average on 56.9 percent shooting.
