Rockets coach Rudy Tomjanovic underwent a 30-minute procedure to test some abnormalities found on his bladder reports Jonathan Feigen, of the Houston Chronicle.

Tomjanovic underwent tests last month when he had a bladder infection. It wasn't until Friday that he learned of the abnormalities the test results showed.

After the Rockets win over the Phoenix Suns on Sunday, Tomjanovic gathered his team and told them of his condition.

Tomjanovic will miss tonight's game against the Seattle Sonics, but is expected to return to the team as early as Wednesday, when the the team will begin it's five-game road trip in Portland.
