UMBC vs. Virginia

UMBC's Cinderella run to the NCAA men's soccer tournament semifinals has seen the Retrievers knock off national powers Creighton, Louisville and Maryland. Now they face their toughest test yet. Cavaliers forward Darius Madison is a Philadelphia native and Union academy product who has a real chance to play at PPL Park in the years to come.

The winner will face the winner of the other semifinal between Providence and UCLA (7:30 p.m. Friday, ESPNU) in Sunday's title game (12:00 p.m., ESPNU).

You'll want to pay attention to the Bruins. Their roster is stacked with prospects for next month's MLS SuperDraft, which will be held here in Philadelphia. Three players - forward Abu Danladi, midfielder Leo Stolz and defender Michael Amick - are in the top 15 of TopDrawerSoccer.com's big board.

Last weekend, Newcastle pulled off a shocking upset in the Premier League when it dealt Chelsea its first loss of the season.

Napoli at AC Milan
