Jackson formerly did radio play-by-play broadcasting duties for the 4th and 5th innings of Phillies home games.
Jackson, an Upstate New York native, started his professional career broadcasting for the Utica Devils after graduating from Syracuse University.
In 1993, he became the radio play-by-play broadcaster for the Philadelphia Flyers, replacing Gene Hart, who had gone back onto television.
He has been the play-by-play voice of the Flyers on television for 31 seasons, now covering the games on NBC Sports Philadelphia.
In 2010, his role was expanded to include play-by-play during the fourth and fifth innings of all regular season home games that did not conflict with his Flyers schedule.
