Dubnyk made a nice pad save on a streaking Marian Hossa before the posts were dislodged when the right winger and Edmonton centre Teemu Hartikainen converged on the goal. Hartikainen practically skated over the prone Dubnyk, who was down for several minutes before he was escorted from the ice.
A trainer appeared to be examining Dubnyk's head and neck.
Yann Danis came in for the Oilers, who had a 4-2 lead at the time of the injury.
If you want to prove people wrong, you've just got to go out and do it. Yeah, we blew 3-2 series leads the last two years, but no one is going remember that if we go out there on Saturday night and beat these guys and go play in the Stanley Cup Final. We need to get back to work and we'll start to do that tomorrow.
