No. 1 Indiana lost forward Austin Etherington during the first half Saturday night against Central Connecticut State.
The sophomore forward appeared to hurt his left leg on a play underneath the basket with the Hoosiers leading 49-29 and 2:28 to go in the half.
He stayed down on the floor as trainers appeared to cover the leg with a towel and almost immediately called for help. Etherington was then lifted onto a stretcher and was surrounded by teammates and coaches.
Team officials did not have immediate details about the injury.
Losing Etherington is another blow to a team that has played all season without forward Derek Elston (knee surgery) and freshmen Hanner Mosquera-Perea and Peter Jurkin, who were suspended by the NCAA for accepting improper benefits from an Indiana booster.
