Reiner, a 6-11, 255-pound junior, sprained the medial collateral ligament in his right knee after scoring nine points and grabbing 10 rebounds against the Buckeyes. He has started all 16 Iowa games this season, averaging 8.1 points and a team-best 8.8 rebounds per game, while shooting 48.8% from the field and 75% from the free throw line. Reiner leads the team with 25 blocked shots.
"Because of our lack of depth any injury for this team is magnified," said Iowa Coach Steve Alford. "It's nice that we have a week to prepare for our next game, but once February is here we have a very busy schedule. Our other guys will have to step up to fill Jared's minutes."
In a Jan. 15 win over Illinois Reiner suffered a spiral fracture in the top of his right hand, but after missing two days of practice he was in the starting line-up in games last week against Wisconsin and Ohio State.
"I feel for Jared, because he has worked extremely hard all season," added Alford. "He is having his best season by far on the court, and he has assumed a leadership role as well. He did a good job of playing with the hand injury. For his sake, I hope the knee injury heals as quickly as possible."
Iowa has posted an 11-5 mark to date, including a 3-2 record in Big Ten play. The Hawkeyes return to action Feb. 1, hosting Purdue at 7 p.m. in Carver-Hawkeye Arena.
