Flames rookie Matthew Tkachuk's chin-high elbow on the Kings' Drew Doughty in Sunday's game likely will get the league's attention.

The late first-period elbow knocked Doughty down and out for the rest of the period. He returned in the second period of a 5-2 Flames win but afterward offered a not-so-flattering assessment of the rookie's play.

"He's a pretty dirty player, that kid," Doughty told reporters, via L.A. Kings Insider. "To be a rookie and play like that is a little surprising. I don't know exactly what happened because I got hit in the head, but I thought he elbowed me. ... Whatever it was, it hurt pretty bad, and it's going to hurt for a bit."
