Jon Miller and Joe Morgan's 21-year run on ESPN's "Sunday Night Baseball" is over.

Morgan's contract is expiring and he will not be renewed. Miller's contract is also expiring though he may remain at ESPN working the "Sunday Night Baseball" series and postseason baseball for ESPN Radio.

"Jon and Joe have contributed greatly to the success of 'Sunday Night Baseball' for the past 21 seasons," ESPN executive vice president Norby Williamson said in a statement Monday. "Over the last two decades, Joe went from Hall of Fame player to one of his sport's top analysts and Jon's Hall of Fame voice and tremendous knowledge of the game have connected with baseball fans everywhere. We owe them our deepest thanks for an outstanding body of work."

Miller, the play-by-play voice, received the Baseball Hall of Fame's 2010 Ford C. Frick Award. Morgan, the color commentator, was a two-time National League MVP with the Cincinnati Reds. The second baseman was elected to the Hall of Fame in 1990.
