Mann's departure will not affect the school's Academic Progress Rate (APR) because of his academic success. Mann will be a "1-1" in APR parlance for the spring semester.
"I've decided to transfer to another school that will provide me a better opportunity to play earlier in my career," Mann said. "I've enjoyed my time at Iowa State and wish the program the best."
Mann saw limited time in his freshman campaign, logging 43 minutes in 18 games. He averaged 0.7 points and 0.4 rebounds. He will have three years of eligibility remaining.
