The school says the 6-foot-4 redshirt freshman will undergo arthroscopic surgery Tuesday morning at the UConn Health Center in Farmington.
The school says the surgery also will tighten up muscles to stabilize a painful condition that has bothered Purvis since high school.
The tear and condition were discovered during an MRI done earlier this year.
The school says it made the decision to have the surgery now, while Purvis is sitting out under NCAA rules following his transfer.
Purvis will have three seasons of eligibility at UConn beginning next fall.
