Melissa Stark will not return to ABC's ``Monday Night Football'' for a fourth season as a sideline reporter because she is pregnant.

Stark is expecting her first child in September. She has worked Monday night games since 2000, when she and Eric Dickerson replaced Lesley Visser on the sidelines. Dickerson left after two seasons.

ABC Sports vice president Mark Mandel said Tuesday the show is seeking a new reporter for the 2003 season.
