"We're hopeful that we'll be able to get him on the court tomorrow, but we won't know anything until he starts running up and down the court. I do know this for sure, he won't be 100 percent, so we'll have to make a decision whether to play him or not."
Lawson suffered the injury less than two minutes into Saturday night's Las Vegas Invitational title game against BYU.
"I turned to go back to offense ... and I just stepped on it wrong and heard a pop," he said Saturday night after the game. "I couldn't run full speed, so I was like, ‘I'm done with it.'"
Lawson is averaging 10.6 points and 4.8 assists through this season's first five games. As a freshman, he earned ACC all-rookie team honors and led the league in assist-turnover ratio.
