No. 4 seed Florida (25-8) vs. No. 5 seed Virginia (23-10)

Second round, East Region; Orlando, Florida; 8:40 p.m. EDT

BOTTOM LINE: Matchup features two of the nation's top defenses, so don't expect a high-scoring affair. The Cavaliers rank second in the country in defensive efficiency, two spots higher than the Gators. ``It's going to be a war of attrition,'' Virginia coach Tony Bennett said. Added Florida coach Mike White: ``It's going to be smash mouth.'' Gators point guard Kasey Hill may have summed it up best: ``I wouldn't be surprised if it's 0-0 for the first 5 minutes. First one to 50'' wins, Hill quipped.

MAN DOWN: Virginia forward Isaiah Wilkins, the team's leading rebounder, is doubtful to play because of strep throat. The 6-foot-7 junior is averaging 6.8 points and 6.0 rebounds. He also leads the team in blocks (43) and steals (33). ``He's has been the heart and soul of our defense,'' Bennett said. ``This virus is hanging on. He's lost some weight and just can't. ... I'm not expecting him to play, but you never know.''

BOUNCING BACK: Florida guard KeVaughn Allen, the team's leading scorer, is looking to end a three-game shooting slump. Allen has made 10 of 37 shots (27 percent) in his last three outings, including 7 of 26 from 3-point range. He was 1 for 11 in the opening round. ``It'll be good just to see the first shot go down,'' Allen said. ``I've just got to continue to stay aggressive.''

DID YOU KNOW: Virginia and Florida last played in the second round of the 2012 NCAA Tournament. The Gators won that one in dominating fashion, 71-45.
