Thompson is the brother of former Newcastle Eagle Andrew Thompson, and also played basketball for Catawba College in the USA.
Worcester director of basketball Paul James is pleased to have experience in his side in the form of the 24-year old.
James said: “Stuart has had an interesting upbringing to his game. He represented his country at junior level, before taking the same path as his brother Andrew in going over to college in the States.
“He has put together some useful numbers which I will now be looking for him to carry over into his game at the Wolves.”
Thompson was delighted to have signed for the Wolves.
He said; “I’m very happy to be joining the Wolves. It’s a team that has already started its climb to the top and I’m glad I can be a part of the success. I’m looking forward to an exciting and competitive season.”
