With Brown's stunning win over Yale and Union's triumph over Quinnipiac in a record-setting series, St. Lawrence will face Union in the night game Friday in Albany.
Brown will be up against Cornell in hopes of continuing its remarkable run in the ECAC Hockey tournament. The Bears finished the regular season 11th and knocked off RPI and Yale to advance to the semifinals.
St. Lawrence, meanwhile, toppled Clarkson in round one and swept Colgate in the quarterfinals.
Now, the Saints have one game to avenge two regular-season losses to Union. The Dutchmen, under ECAC Coach of the Year Nate Leaman, beat the Saints 4-3 and 4-2.
The teams have not met in the playoffs since 2001 when St. Lawrence swept Union.
A full preview will come later in the week. The puck drops at 7 p.m. pending the conclusion time of the afternoon game between Cornell and Brown.
