PREGAME

St. Joseph's Prep will start with the ball after winning the toss and electing to receive.

La Salle rolled to a 48-0 win at Cardinal O'Hara last week, and early-season victories over Malvern Prep and Harrisburg have gained weight in recent weeks.

The Explorers will need to pass a big test this week to stay at No. 1 in Pennsylvania. They're led by the top-ranked junior in the state, 6-foot-4 WR/DB Joey O'Brien, who pairs with senior Syracuse commit Julian McFadden to form a lethal receiving duo.

St. Joseph's Prep opened division play with an easy 42-13 win over Father Judge last week, with wide receiver Jett Harrison continuing to look nothing like a typical freshman.

Senior Ohio State commit Isaiah West leads the Hawks' running game.

The Prep has a chance to stamp itself as the No. 1 team in the state with a win this week.
