Arizona Loses Game and Leading Scorer: Arizona’s loss against North Carolina cost them their leading scorer, Marcus Williams, who went down with an apparent ankle injury Saturday. The Wildcat sophomore rolled his right ankle while landing after a jump shot. He was carried off the court and taken to the locker room with 4:47 remaining in the first half. Williams is averaging 18.1 points and 7.6 rebounds in 18 games this season, and there is no word on his return. [1/29/07]
