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.
For six months, it's a really good accomplishment. But as soon as April [11, the end of the regular season] comes around, no one thinks about the regular season anymore.
