Jose Calderon broke his nose after colliding with Tony Parker during the second half of the Mavericks' Game 6 victory on Friday. Calderon briefly returned to the court but he found it "tough to breathe" and was forced to ask for a substitution. "I hope I'm better in Game 7. I think we were trying to stop the bleeding, so there was a lot of stuff up my nose," Calderon said. "I think it was that more than anything else with the breathing." Doctors will determine whether Calderon should wear a protective mask for Sunday's decisive game in San Antonio.
