Brent Seabrook scored on the power play to put the Blackhawks up two goals in the first period.
The Blackhawks squandered that lead the rest of the way and watched as Mark Scheifele scored the overtime winner as Chicago lost 3-2 to the Jets on Saturday night at the United Center.
The game started out well, as Robin Lehner, in for his first game, made two quick stops within the first few minutes, and looked comfortable. Calvin de Haan, who was playing in his first game with the Blackhawks, also impressed, and Brendan Perlini figured in for his first game of the season.
