Two days after upsetting then-No. 5 Kansas State, Florida suffered an upset of its own.

Keith McDougald scored 18 points, including two clutch free throws with 18 seconds left in overtime, to help Jacksonville stun the 19th-ranked Gators, 71-68, in a Monday afternoon game in Gainesville.

Jacksonville (7-3) led for much of the game, before the Gators rallied midway through the second half. Florida (8-3) led by seven with six minutes to play, but couldn't hold the lead. The Dolphins closed with a 12-5 run, capped by Ayron Hardy's steal and dunk with 18 seconds left that sent the game into overtime, tied 61-61.

Erving Walker led the Gators with 21 points, but missed a potential winning jumper at the end of regulation. Florida shot 35.4 percent from the field and turned the ball over 17 times.

Florida will try to rebound against Radford Wednesday. Jacksonville gets 10 days off to enjoy the upset, before hosting Bethune-Cookman on Dec. 30.
