ECAC quarterfinals will be held Friday and Saturday, with Harvard hosting Colgate at 7:30 p.m. each night. Each playoff match-up will be a two-game series. It is not a total-goals series.

If the two teams split the series, a 10-minute mini-game will be played. If the mini-game is tied, the squads will play sudden-death overtime periods until one scores.

Tickets for the Harvard-Colgate series go on sale today at the ticket office in the basement of Harvard Hall (four dollars for undergraduates with coupon, six dollars otherwise).
