Guildford Heat have signed centre Ajou Deng, the elder brother of Chicago and Great Britain star Luol, to replace American Steve Allen.
The 6ft 11in Deng played for the Heat two seasons ago but missed the whole of last season through injury.
Deng, 28, has previously played for Brighton and the Scottish Rocks in the British Basketball League.
Allen was let go after a disappointing debut for the Heat in Tuesday's 40-point home defeat by Ankara.
I expect him to slot back into the side quite easily
Guildford coach Paul James
Deng averaged 13.6 points and 11.2 rebounds per game with the Heat in their debut season two years ago.
He spent a large part of last season in Chicago receiving treatment and rehabilitation for a persistent ankle injury.
"Ajou is a well-liked player and has great skills and knows our club," said Heat coach Paul James. "I know he has benefited greatly from the medical staff at Chicago Bulls.
"Ajou has been training with the Bulls regularly for some time and I expect him to slot back into the side quite easily."
