Nick Headrick scored in the dying seconds of overtime to lift the Castlegar Rebels past the Nelson Leafs 2-1 on Saturday.
Headrick capitalized on a power play with just 46 seconds left in the contest for the Rebels' third straight win.
Darren Medeiros also scored for Castlegar (27-12-2), while goaltender Paul Broadbent finished with 22 saves.
Patrick Ostermann replied with 38 saves for Nelson (17-23-2) with Levi Hulston adding all the offence the team would get.
Medeiros put the Rebels up on the power play 11:14 into the first, but Hulston responded just 28 seconds later. Nelson was lucky to get a goal in the period at all - the Leafs were outshot 13-3 in the first.
The Leafs have lost three straight but secured a playoff spot with Spokane's 5-0 loss to Fernie on Friday.
