Marbury, a former All-Star reportedly scheduled to earn $21.9 million this season, did not play in the Knicks' 120-115 season-opening win over the Miami Heat on Wednesday.
Knicks coach Mike D'Antoni and Marbury met Friday and Marbury asked the coach if he was going to play. When told he would not be seeing action, Marbury reportedly requested he be put on the inactive list and D'Antoni and the guard mutually agreed to take that action for Friday's game.
"This is the direction we're going and there will be some nights like this," D'Antoni said of Marbury after the loss. "If I was playing everything for tonight, you'd do things differently. But we're trying to build a base for going forward."
Marbury was not available for comment after the game.
Dressed in street clothes, Marbury watched from the Knicks bench after not warming up prior to the game.
