Winners in each of their first seven games, the Lancers have dropped back-to-back decisions with a 3-1 loss to the Waterloo-Oxford Crusaders and a 4-1 defeat to the Huron Heights Huskies.
The results mean the Lancers (7-2) now trail the Huskies (8-1) by one game with each team having one game left in their regular-season schedules. The Bluevale Knights (7-2) also have one game remaining, while the fourth-place Cameron Heights Golden Gaels (6-1-2) are waiting for the playoffs to start.
Huron Heights has the WCI Vikings (1-6) in its final game and, barring an upset, the defending champions will be ranked first heading into the playoffs.
