Playing just 16 minutes in Duke's opening round blowout of Alabama State, Duhon was held scoreless and attempted just one shot.
"There are times when I'm scared to penetrate because I don't want to get the contact," Duhon said of his injury. "We'll see how it feels. That's something I have to get over."
