He's only the second point guard to win the award along with Tar Heel legend Phil Ford in 1978.
Lawson has been dealing with an injury to his big right toe. When doctors examined his foot last week, they determined his latest injury was in the same place as an old injury.
Coach Roy Williams said in a news conference Tuesday that he would not hesitate to bench Lawson in order to rest his toe.
By resting during the ACC tournament, Lawson will hopefully be able to play in the NCAA tournament. It is not clear is Lawson will play later this week if the Tar Heels advance.
