Nunge suffered the injury while driving to the basket late in the first half of Sunday's 85-59 win over Cal Poly. Nunge sat out the rest of the game, and an MRI later showed the injury.
The 6-foot-11 Nunge was averaging 6.0 points and 4.6 rebounds per game. Nunge redshirted in 2018-19 after playing as a freshman, and the Indiana native will likely seek a medical redshirt to preserve the three seasons of eligibility he has left.
The Hawkeyes play No. 12 Texas Tech on Thursday in Las Vegas, with senior Ryan Kriener expected to take Nunge's spot in the starting lineup.
