Clemson dazzled in its ACC opener against Wake Forest but likely will be less than whole in the second outing. Big man Carter Welling -- the Tigers' top rebounder and shot blocker as well as the No. 2 scorer -- suffered a knee injury. North Carolina is figuring out life without ailing standout Caleb Wilson, gone for the season. The Tar Heels beat Clemson by four points two weeks ago minus Wilson, albeit at home. Their weakness -- rebounding -- could be mitigated by the probable absence of Welling.
