The former Knicks point guard made good on his promise to show up for his former team's home opener and sit in the front row. But Marbury was asked to leave those seats when ushers examined his ticket and determined he was sitting in the wrong spot.
Rather than relocate, Marbury left the arena just as the first quarter was ending.
Adding to the bizarre scene, Marbury pulled out a video camera shortly after arriving and began shooting the live action, at one point standing up -- thereby blocking the view of the fans behind him -- while play was ongoing.
A Madison Square Garden security official spoke to Marbury during a timeout, and it was then discovered that Marbury was holding a ticket for Row A. But the seat he was occupying -- just a couple chairs down from Spike Lee's regular seat -- was actually in Row AA, and Marbury was asked to move.
After turning down a $1.99 million, one-year offer from the Boston Celtics early in the summer, Marbury remained unsigned through the summer. He recently said he plans to sit out the entire 2009-10 season before making a comeback next season.
