Tillie is planning to sign a contract to play for Unicaja Malaga in both the ACB and Basketball Champions League during the 2024-25 campaign, Eurohoops reports.
Tillie hasn't seen NBA regular-season playing time since 2021-22, but he saw action with the Celtics during the 2024 Summer League, averaging 8.4 points and 3.8 rebounds in 17.2 minutes across five appearances. This is Tillie's first taste of overseas action since debuting professionally with INSEP Paris in 2014-15.
