Islanders' Seidenberg injures Oilers' Puljujarvi with knee-on-knee hit
This won't make Dennis Seidenberg a popular man in Edmonton.
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.
