Utah Jazz small forward Andrei Kirilenko has left the team's road trip because of back spasms, the club said Wednesday.
He will be evaluated by back specialists on Thursday and Friday, and the results are expected Friday afternoon or Monday.
Kirilenko, who missed seven games last month with a sprained right ankle, had to leave Saturday's game in Milwaukee after just 17 minutes with the back problem, and he sat out Tuesday night's game at Cleveland.
The Jazz lost 101-89 at Boston Wednesday night and end their road trip Friday at New York.
