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.
It's cool when you think about how many great American players have played the game and the two players that were at that 18-game point streak and what they've done in their careers. It's pretty cool right now, but it was kind of overshadowed by the loss.
