White sat out Thursday's practice in an attempt to heal the injury, which is affecting his right shoulder and neck.
Hawkeyes coach Fran McCaffery says the coaching staff is unsure of White's status, adding that White will likely try to practice Friday in an effort to see if he can play against the Badgers.
Key substitute Gabe Olaseni rolled his left ankle on Monday. Olaseni says he'll be ready by Saturday, though his effectiveness won't be known until tip-off.
