The injury suffered during a pickup game not only is personally devastating, but also damaging to the Hokies' chances this season of getting back to the NCAA tournament.
The Hokies barely missed getting a bid last season and return most of a 25-win team that went to the NIT, but Thompson is the second forward to go down this offseason.
Allan Chaney fainted during an individual workout in April, and the transfer from Florida could be lost for the season due to a heart ailment.
The team's sixth man, Thompson averaged 7.3 points and 4.6 rebounds per game last season. The silver lining is that he could redshirt and play as a senior next season.
"I am extremely disappointed for JT, suffering an ACL injury that will result in a season-ending surgery," coach Seth Greenberg said in a statement. "JT is a huge part of what we have been able to accomplish over the last three years. His work ethic, energy, toughness and skill level will most definitely be missed. At this time, we need to be there for JT. I am sure that players already in the program will step up when given the opportunity. We expect JT to have a full recovery and know that he will still find a way to contribute this season and be a leader next year."
