Three Rivers is an American television medical drama which debuted on October 4, 2009 on CBS, starring Alex O'Loughlin at the role of a notorious transplant physician at Pittsburgh, Pennsylvania. On November 30, 2009, after eight episodes of this summer season had dipped, CBS announced that Three Rivers had been hauled from their agenda with no plans to have it returned, and the show has been cancelled. Nevertheless, the show later came back to the network on June 5, 2010 to burn off the rest of the unaired episodes.
