Pellom is expected to miss the next five weeks.
“It was a simply and minor procedure, and we expect David back in no time,” coach Josh Pastner said in a statement.
Pellom, a 6-foot-7 forward, transferred into the program from George Washington in the spring. He averaged 10.4 points and 6.1 rebounds two seasons ago with the Colonials, but sat out 2012-13 after injuring his wrist while recovering from meniscus surgery on his left knee. Pellom was able to play immediately as a graduate student.
With Pellom on the mend, Pastner will lean on a host of youngsters to pick up the frontcourt minutes. Freshmen Nick King and Kuran Iverson can play both forward positions, while classmate Austin Nichols could see increased minutes inside. Sophomore forward Shaq Goodwin will be the elder statesman down low, after averaging 7.4 points and 4.4 rebounds last season.
