Indiana starting point guard Xavier Johnson suffered a foot injury in the first half and did not return during the the No. 14 Hoosiers' 82-64 loss to No. 8 Kansas on Saturday.
Johnson suffered the injury with 9:12 remaining in the first half while scrambling for a loose ball and needed to be helped off the floor. He immediately went into the locker room and came back to the bench in the second half on crutches with his right foot in a boot.
Coach Mike Woodson said after the game he didn't know the extent of Johnson's injury, but that it didn't "look good."
"He couldn't play the second half," Woodson told reporters. "We've gotta go back and get him evaluated and see where we are."
Kansas led 23-12 at the time of Johnson's departure and the Jayhawks went into halftime with a 44-29 lead.
Johnson, a 6-foot-3 senior, had started each of Indiana's first 11 games after starting 34 of 35 games last season. He was averaging 10.9 points, 3.5 rebounds and 5.2 assists entering Saturday's game, shooting a career-high 38.5% from 3-point range.
Indiana (8-2) next hosts Elon on Tuesday and Kennesaw State on Friday before Big Ten play begins in early January.
