The last 47 seconds of the game. . . The Purdue Boilermakers were beat up but smiling. Fifth-seeded Purdue held off a late charge by 12th-seeded Northern Iowa for a 61-56 victory Thursday in a rugged first-round game, and showed it afterward. E'Twaun Moore had his right shoulder encased in ice and wrapped in plastic after his game-high 17 points. Robbie Hummel, who had both knees similarly sheathed, had nine points and a game-high 12 rebounds.
