Steve Clifford, the Bobcats' rookie coach, was hospitalized Thursday night and could miss the team's home game against the Knicks on Friday, the team announced.
Clifford, 52, checked himself into a Charlotte-area hospital saying he didn't feel well. Doctors kept Clifford overnight and are continuing tests Friday.
Bobcats assistant coach Patrick Ewing would likely assume Clifford's duties if he is unable to coach against the Knicks.
Clifford has the Bobcats off to a 3-2 start, a half-game behind the first-place Heat in the Southeast Division.
Ewing, a former Knicks great, said he hoped Clifford will be back in time for Friday's game, but he would be ready if he can't.
