The 6-foot-8, 248-pound forward from Dubuque averaged 5.9 points, 4.3 rebounds and 1.2 assists over 96 career games. Pemsl, who had three major surgeries over the past six years, was a reserve exclusively after starting 14 games as a freshman.
He did not say where he hopes to play.
"I would like to thank my teammates, coaches, and fans for a memorable four years at the University of Iowa," Pemsl said Friday. "I am grateful for the support Hawkeye Nation has shown me through many difficult times. With that being said, I am going to finish my degree and plan on completing my final year of eligibility at another school next season."
