SAN LUIS OBISPO, Calif. (AP) _ Larry Welsh is out as football coach at Cal Poly-San Luis Obispo, completing a third straight losing season in which his team has lost four straight games.

He will coach his final game at the school Saturday when the Mustangs end their season at home against Youngstown State. His team is 3-7 and he has a 19-24 record in nearly four years.

Athletic director John McCutcheon said Tuesday that Welsh will be replaced at season's end.

``I challenged the team to stay together and play for their assistant coaches in this weekend's game with Youngstown State,'' Welsh said. ``This team played hard every game.''

In Welsh's first season, Cal Poly was 10-1 in 1997 and nearly made its first playoff appearance since the school moved up to Division I-AA in 1994. But the Mustangs stumbled to 3-8 records in 1998 and '99 playing improved schedules.

``Coach Welsh has done some very positive things with our football program,'' McCutcheon said. ``He has recruited several outstanding student-athletes and our program is positioned for the future.''
