BLOOMINGTON, Ind—Jordan Hulls scored 12 of his 18 points in the second half, and Tom Pritchard’s tip-in with 44.2 seconds left led the Indiana past No. 20 Illinois 52-49, setting off one of Bloomington’s wildest postgame parties in years.Hulls, who was sick Sunday at Iowa, started the game with a wrap on his right knee and finished it with a bandage on his right temple, tape around his right forearm and blood on his shorts.Pritchard, who drew four fouls in the first nine minutes of the second half, came up with the game’s biggest play when he got his fingertips on a missed shot and redirected it in for the go-ahead basket, just his second all night. Indiana’s Christian Watford, who had 16 points, had blood on his jersey.But none of that mattered to Hulls, who scored more than half of Indiana’s 22 second-half points while three of the Hoosiers’ projected opening-day starters — guards Maurice Creek and Verdell Jones and center Guy-Marc Michel sat on the bench in street clothes. Creek and Jones were out with knee injuries. Michel was declared ineligible by the NCAA in December.After ending a 19-game losing streak against Top 25 teams, Crean traded high-fives with fans who stormed the court. Students jumped up and down at midcourt as Hulls tried to finish a television interview, and some of the Hoosiers got in on the act, too, before heading to the safety of their locker room where the celebration continued.The last time Indiana (11-10, 2-6 Big Ten) had beaten a ranked foe: Feb. 19, 2008 against Purdue.Mike Davis led the Fighting Illini (14-7, 4-4) with 14 points, but nobody else reached double figures. Demetri McCamey finished with six points, his second straight game with fewer than 10, and Illinois’ vaunted 3-point shooters were a dismal 5 of 20.Illinois has lost four of its last five.
