ANALYSIS: Dallas head coach Rick Carlisle had this to say this morning, "I had an unexpected positive test. There's a chance and a hope that it will be a false-positive." Brad Townsend of the Dallas Morning News went on to say that Carlisle says he has been fully vaccinated since January, and there was hope that he would be able to coach if the new tests came back negative, but ultimately he was ruled out of tonight's matchup with the Knicks.
