Marcus Jordan scored 18 points, Keith Clanton hit two free throws in the final seconds, and Central Florida upset No. 18 Florida 57-54 on Wednesday night in Orlando.
The Gators, ranked ninth in The Associated Press pre-season poll, lost to the Knights for the first time in 10 meetings and could drop from the rankings after another lackluster effort.
"Our issues are bigger than this loss," said Donovan, whose team eked out wins over Morehead State, Florida Atlantic and Florida State. "We have a bunch of guys on the floor that make nobody better."
Donovan said he is considering making changes, possibly as drastic as swapping some of his veteran starters for newcomers.
Michael Jordan's son had a lot to do with this one.
Jordan was 6-for-11 from the field and played tight defense, creating all kinds of problems for the Gators (5-2). He clamped down on Florida's leading scorers, Kenny Boynton and Chandler Parsons, and broke down Florida's perimeter defense at will. His biggest shots came at the free-throw line. He hit two with 24 seconds remaining, putting the Knights (6-0) up 55-52.
Erving Walker and Boynton missed three-pointers, and Clanton made two free throws that pretty much sealed it.
South Carolina 74, Delaware State 61: Lakeem Jackson, Brian Richardson and Malik Cooke scored 12 points each to lead the host Gamecocks (5-1), who won their fourth straight. South Carolina led by as many as nine points early but trailed 37-35 at the half.
Arkansas 84, Oklahoma 74: Rotnei Clarke scored 20 points, connecting on three of five three-point attempts, and Arkansas held on in the second half at home. Ten players scored for the Razorbacks (4-1), who were coming off their first loss of the season against Alabama-Birmingham.
No. 14 Memphis 78, Arkansas St. 71 (OT): Will Barton scored 20 points, and the host Tigers survived a scare with an overtime victory. The game was tied at 65 at the end of regulation, and Arkansas State got two quick baskets in the extra period. But Memphis (6-0) scored the next seven points to pull away and escape with its undefeated record intact.
No. 22 Purdue 58, Virginia Tech 55 (OT): JuJuan Johnson started fast, and finished even better. Purdue's big man scored 29 points, including a go-ahead 15-footer with 1:27 left in overtime, and the visiting Boilermakers clinched the ACC/Big Ten Challenge for the Big Ten for the second straight season.
Miami (Ohio) 75, Xavier 64: Julian Mavunga scored a career-high 24 points and Miami pulled off the upset at home. Nick Winbush scored 15 of his 17 points in the second half to help the RedHawks (3-4) take a 14-point lead with 5:32 left in the game. The Musketeers cut it to two, 64-62, on a pair of free throws by Mark Lyons with 2:41 left. Mavunga followed with two free throws, and Chris McHenry made a desperation three-pointer as the shot clock expired with 1:45 left in the game, helping the RedHawks snap a three-game losing streak.
Boston College 88, Indiana 76: Reggie Jackson scored 27 points, grabbed five rebounds and dished out four assists to lift the host Eagles in an Atlantic Coast Conference/Big Ten Challenge matchup.

West Virginia 71, American 50: Casey Mitchell continued his run of high-scoring games, pouring in 27 points to lead the Mountaineers. Kevin Jones added 16 points for WVU (5-1), which played its first home game since Nov. 18.
Hanover 68, Transylvania 60: Freshman Ashley Hatfield out of Shelby Valley scored a career-high 19 points, but it wasn't enough to stop host Hanover in the Heartland Conference opener for both teams. Montgomery County graduate Brandon Rash added 15 points before fouling out for Transy (2-2, 0-1).
Thomas More 65, Grove City 44: Colt Stafford scored 17 points in 19 minutes, and Henry Clay graduate Aaron Miller added 15 points and seven rebounds as the host Saints (3-2) won their Presidents' Athletic Conference opener.

Hanover 63, Transylvania 59: Olivia Akridge, a senior guard out of Lyon County, scored 14 of her 18 points in the second half, but the host Pioneers couldn't complete a rally after falling behind 25-19 at halftime.
Tuesday's late game
No. 20 Illinois 79, North Carolina 67: Mike Davis scored 20 for the Illini, but Demetri McCamey was the leader, finishing with 17 points and eight assists and helping four teammates score in double figures. He guided a tough perimeter defense for Illinois (7-1) that put the Tar Heels (4-3) in a hole early and kept them there.
North Carolina center Tyler Zeller picked up three early fouls and spent more than nine minutes of the first half on the bench. John Henson led UNC with 16 points, and Zeller finished with 10.
