Shannon, the team's longtime radio broadcaster, is 80 and gave up doing road games four seasons ago. But he is scheduled to be on the call for all Cardinals postseason games this fall. John Rooney, who broadcasts home regular-season contests with Shannon, and Ricky Horton, who does road games with Rooney, will team with Shannon to form a three-man booth. They won't all work simultaneously for the most part, but generally two will be on together.
