Hartman undergoes successful knee surgery; diagnosis not revealed

Collin Hartman underwent successful surgery on his injured left knee this week, Indiana announced Wednesday.

Whether the senior will be available at any point this season remains unclear.

IU did not disclose Hartman’s diagnosis in the update posted to the basketball program’s Instagram account, other than noting that Hartman’s “rehabilitation begins immediately and it is too early to determine a timetable for his return.”

Hartman originally sustained the injury in a non-contact drill during individual workouts on Sept. 20.

“Any time you see one of your players go down to injury, it tears you up as a person and as a program — even more so when it’s someone like Collin Hartman, who has been a huge part of our success and is in his senior year,” IU coach Tom Crean said in a statement. “We all look forward to helping him recover and rehabilitate.”

This is Hartman’s second knee surgery in two years. He injured the ACL in his right knee after his freshman season in 2014, but rehabbed and returned quickly enough to play 32 games during a breakout sophomore year.

Hartman averaged 5.0 points and 3.1 rebounds per contest as a junior, starting 24 of the 35 games in which he appeared.

Shortly after the season ended, it was believed that Hartman would require surgery to repair a fractured right wrist. Ultimately, Indiana did not pursue wrist surgery, placing Hartman in a cast instead.

Indiana will conduct its first practice of the preseason on Friday.
