Representatives from the Catholic Athletic Assn. approved new leagues on Thursday, and for football only, L.A. Salesian was put in a league with Loyola, Bishop Amat and Gardena Serra. Salesian will appeal the decision to the Southern Section.

Salesian won the Northeast Division last season. That's considered Division XIII in strength. Salesian has been adding transfer students in recent years, alienating some of its member schools, and that probably helped influence other schools to vote in favor of adding Salesian to the more powerful league. Another proposal would have put Cathedral in the league.

That league is expected to be placed into the Pac-5 Division, along with the league made up of Crespi, Notre Dame, Chaminade and Alemany.

They will be considered Catholic League North and Catholic League South, and each school will play the other during the season as part of crossover nonleague games.

The new Mission League for football only will be made up of Cathedral, St. Francis, La Salle, Harvard-Westlake and St. Paul.

In more re-leaguing news, Newbury Park has decided to file an appeal after the Panthers were put into a league last week in the Northern Area with St. Bonaventure, Oaks Christian, Westlake, Camarillo and Thousand Oaks for football only.
