Toronto Raptors centre Aaron Gray is out of action indefinitely while he undergoes further monitoring and testing for a rapid heart rate.
The Raptors decided to withhold Gray from game action after consulting with league cardiologist Dr. Allan Schwartz. Gray will still be able to participate in full contact practices, the team said Friday.
Gray signed with the Raptors on Dec. 11 as a free agent. He had nine rebounds in 32 minutes over two pre-season games.
Toronto split its first two games of the regular season and was set to kick off a three-game road trip Friday night against the Dallas Mavericks.
