RALEIGH, N.C. -- North Carolina State says guard Markell Johnson will be a game-time decision for the Wolfpack's Atlantic Coast Conference Tournament opener next week with a sprain and a bruised bone in his left knee.

Team spokesman Craig Hammel announced the diagnosis Friday, two days after the freshman injured his knee during a loss at Clemson in the regular-season finale. He says Johnson underwent an MRI on Thursday night.

Johnson averages 4.0 points as a reserve for the Wolfpack (15-16, 4-14), who begin ACC Tournament play Tuesday against an opponent to be determined.
