This won't make Dennis Seidenberg a popular man in Edmonton.
The New York Islanders defenseman caught Oilers rookie Jesse Puljujarvi with a knee-on-knee hit midway through the opening period Saturday night.
Puljujarvi left the game and was ruled out for the remainder shortly thereafter.
The 18-year-old posted three points in his first nine NHL games prior to Saturday's contest. He was selected fourth overall by the Oilers in June's draft.
