So far this is what I have seen about him playing.
Got this from the NY Times.
Marbury sat on the bench wearing a dark brown suit. He injured his shoulder against the Minnesota Timberwolves on Monday. Brown did offer Marbury the option of playing a couple of token minutes to keep his streak alive, saying, "It's an incredible streak when you consider the bumps and bruises he gets."
Marbury, though understanding of Brown's intentions, respectfully declined.
"I don't want my kids to look back and say, 'My father went on the court just to keep up the streak,'" Marbury said. "That's cowardly to me. It's like trying to uphold something that shouldn't be upheld by going on the court and coming back off. If you can't play, don't play."
Marbury said doctors had told him that he could recover within nine days.
Should that prognosis hold true, Marbury would miss Thursday night's game against the Detroit Pistons, Saturday night's game against the New Orleans Hornets and he would be questionable for next Wednesday's game against the Sacramento Kings.
