Indiana senior forward Collin Hartman had successful surgery on his left knee on Monday and is now set to begin his rehabilitation.
Hartman suffered the left knee injury on Tuesday, Sept. 20, during a non-contact drill, IU said on Sept. 21.
Indiana did not specify the nature of the surgery nor did it make any reference to expecting Hartman back on the court this season.
“Anytime 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.
“We all look forward to helping him recover and rehabilitate.”
Hartman tore his right ACL in March of 2014 in a workout. Hartman rehabbed in time to play in 32 games as a sophomore in 2014-15.
A 6-foot-7 senior forward, Hartman started 24 of the 35 games he played as a junior in 2015-16, averaging 5.0 points and 3.1 rebounds.
Hartman was an Indiana All-Star who led Indianapolis Cathedral to the Class 4A state title game as a senior.
He was expected to be an experienced part of a deep front line for Indiana this season.
IU won the Big Ten regular-season title and reached the Sweet Sixteen last season.
