The 28-year-old forward earned a roster spot with the Raptors in training camp, but was waived before his $1.79MM contract became fully guaranteed in early November. He played just one game for Toronto before being released. Dekker finished the season with Bahçeşehir Koleji of Turkey, which went on to win the FIBA Europe Cup.
Dekker was selected by the Rockets with the 18th pick in the 2015 draft and spent two seasons in Houston before being shipped to the Clippers as part of the Chris Paul trade. He also had brief stints with the Cavaliers and Wizards, and averaged 5.4 points and 3.0 rebounds in 201 total NBA games.
The former Wisconsin star headed overseas after the 2018/19 season, signing with Lokomotiv Kuban in Russia and then Turk Telekom in Turkey.
Dekker will join former NBA center Kosta Koufos, who signed with the London team last month.
