UPDATE: Derek Fisher is active and in the starting lineup. Elton Brand did not dress out.
Carlisle might change his mind after talking to Fisher.
Fisher, who missed this morning's shootaround, is at the American Airlines Center and plans to make a decision on his status after a pregame workout.
"I'm not sure yet," Fisher said. "I'll see how I feel when I get out on the floor."
Forward/center Elton Brand's status is also uncertain. He's been bothered by a sore groin recently.
Sixers point guard Jrue Holiday, who leads Philadelphia in scoring and assists but has missed the last two games with a foot injury, is out again.
