Northern Arizona Vs. Arizona Live Radio Broadcast: College Basketball 2013 (LISTEN)

The Northern Arizona Lumberjacks play the Arizona Wildcats on Monday. Tipoff is at 10 p.m. ET. Listen to the live radio broadcast via the link below.

No. 1 Arizona hosts NAU at the McKale Center in Tuscon, Arizona. The Wildcats look to continue their unbeaten streak and add a 13thh win. The task is made more difficult by the unavailability of center Kaleb Tarczewski, who's expected to miss his second straight game with a sprained right ankle, according to ESPN.

"We're going to take it slow. We want to make surer he's at his best for the Pac-12," Arizona coach Sean Miller said, via ESPN. "I have my fingers crossed that in seven to 10 days from now that he's in a much better place. We're really working hard right now to get him back."

The 7-footer is averaging 10.1 points and 6.7 rebounds per game. The absence of Tarczewski puts more of the offensive burden on the shoulders of junior guard Nick Johnson, who has a team-high 15.7 points per game.

More will be expected of freshman forward Aaron Gordon, who's averaging 12.8 points and 7.8 rebounds per game and is coming off a career-best 21 points against Southern. Despite his performance on offense, Gordon wasn't pleased with his lack of rebounds in the contest.

"Scoring is always good but I didn't rebound well enough at all," said Gordon. "I pride myself on rebounding and to have a rebounding performance like that doesn't make me feel like I had a good game."

North Arizona, meanwhile, is in an early hole with a 3-7 record. Senior forward Max Jacobsen leads the team with 14.8 points, and junior forward Gaellan Bewernick has a team-high 7.5 rebounds per game.
