Disgruntled Rockets center Omer Asik is changing agents, switching from Andy Miller to Arn Tellem of Wasserman Media Group, league sources told CBSSports.com on Tuesday.

Asik's decision to change agents was first reported on Twitter by the Turkish basketball site Superbasket.org. He must submit paperwork to the National Basketball Players Association to formalize the change, and then Tellem must wait 10 days before commencing representation.
