The 24-year-old American, who averaged 19 points, three assists and two steals per game, has signed for BBL side Worcester Wolves.
Speaking on the Wolves website, Prezzie-Blue, said: “I am looking forward to playing for coach James (Worcester’s Paul James) and making an impact for the Wolves.
“I love the style of the coach, and feel that I will fit in well to his system. I think it will be a great season, and I’m looking forward to getting to know the Wolves supporters.”
Prezzie-Blue is the first confirmed departure from last season’s Thunder line-up.
