NO. 18 MICHIGAN ST.: Starting forward Matt Trannon is out indefinitely with a broken jaw. The senior, who was averaging 4.7 points and 4.3 rebounds, was hurt late Saturday when he collided with teammate Shannon Brown and Michigan's Graham Brown.
DUKE ON TOP AGAIN: Duke moved back to No. 1 in the Associated Press poll. The Blue Devils were second the past four weeks to Connecticut, the only other No. 1 team this season but who lost to Villanova last week.
Villanova jumped from fourth to second (the highest ranking in school history), and Connecticut dropped to No. 3. Memphis, the other team to get a first-place vote, fell one place to fourth.
Northern Iowa, which beat then-No. 24 Bucknell in double overtime Saturday, returned after a week out. It's tied for No. 25 with Nevada, which reached No. 17 earlier this season.
ARKANSAS: The school was fined $5,000 by the conference because 20-25 fans rushed the court after Saturday's victory against Florida. The only other school fined this season was Tennessee when its fans rushed the court after a victory against Florida on Jan. 21.
VANDERBILT: Senior guard Mario Moore returned after a medical leave of absence. Neither he nor the school disclosed the reason for the leave that kept Moore, averaging 6.3 points a season after leading the team at 13.5, out since Feb. 7.
MISSOURI: University president Elson Floyd ordered an independent investigation into the departure of coach Quin Snyder. Snyder resigned Feb. 10, one day after saying he would stay for the rest of the season. The Kansas City Star reported soon after that athletic director Mike Alden sent assistant Gary Link to tell Snyder he could resign or be fired at the end of the season. Alden first denied it but Monday said he sent Link to see if Snyder might want to "step away" from the job.
POLL: Tennessee, at No. 5, is ranked for the 500th time. The Vols have appeared in every poll but 14 since it was created in 1976, including the past 373. No. 20 Louisiana Tech is second in appearances with 444. Duke remained No. 1 with 39 of 45 first-place votes. North Carolina, at No. 2, received the others.
