Coach Brett Brown confirmed the suspension during a shootaround before Friday night's game in Brooklyn. He said he had been looking forward to coaching Kirilenko.
It's not clear why Kirilenko hasn't joined the Sixers since the Dec. 11 trade. The deal sent forward Brandon Davies to the Nets for Kirilenko, a second-round pick in the 2020 draft, guard Jorge Gutierrez and cash.
Kirilenko hasn't played since Nov. 13 and has played sparingly in seven games this season. He has cited family matters as part of the reason for his absence.
Brown said he met with Kirilenko after the trade and thought Kirilenko would be part of the team.
