Brett Brown benched Markelle Fultz in favor of T.J. McConnell in Monday's win by the 76ers over the Suns.
Brown wouldn't commit to either Fultz or McConnell as his backup point guard.
"I don't know," Brown said.
Fultz downplayed the situation after the game.
"Our relationship is more than teammates," Fultz said. "We both want to see each other do well, and we want to see the team win, so anytime one of us step on the court, we are probably rooting for each other more than most people. That's how it is.
"You definitely want to go out there and compete ... I'm a competitor. But, at the end of the day, coach made a decision to do that, so I have to live with it. My mindset is just, when I step on the court, go out there and play. But while T.J. is out there, I'm rooting for him.
"It's not like I'm sitting on the bench pouting or anything. I want to be out there, but I'm going to root for my teammates."
