The injury-bug has continued to keep the rotation players of the Rockets from preparing for the regular season and is forcing Rudy Tomjanovich to continue using the time for experimentation with his bench, reports Jonathan Feigen of the Houston Chronicle.  Francis, Rice, Griffin, Williams, and Cato will all sit out tonight game against Orlando with one small injury or other.  They should all be ready for the regular season.  The injuries mean that Dan Langhi, Damon Jones, Tierre Brown, and Jason Collier will get more court-time than they have all preseason.
