The Eagles return home from South Bend with their first win over the Fighting Irish since 2004.
Knight stopped 17 shots in the first period alone and the Eagles offense continued its high-flying ways en route to a 3-0 win.
A bye week was just the recipe for BC, as it returned to roll over N.C. State behind a resilient defensive effort and an impressive rushing attack.
Fusine Govaert scored in the waning minutes of the first half and that was enough for the Eagles as they slipped by the host Cavaliers, 1-0, behind a three-save shutout from Sarah Dwyer.
BC midfielder Joe Kellett scored on a free kick in the 90th minute to force overtime, and the Eagles parked the bus and hung on to escape Blacksburg with a 2-2 draw.
