Ducks coach Bruce Boudreau suggested that the NHL take a long look at a hit by the Kings' Jarret Stoll on Cam Fowler that knocked the defenseman out of the club's 7-4 win and left him with an upper-body injury.

Fowler had to be assisted off the ice during the second period and did not return. Stoll drilled him headfirst into the boards and was not penalized.

The severity of the injury is not known but Fowler is expected to be re-evaluated on Sunday.
