"He will contribute and be an important piece for us. Then it's about patience, just like with all other players who come from North American hockey. Even if Oliver is Swedish, it will be an adjustment for him", says the sports manager Niklas Wikegård to the club's website.
Kylington has previously played for, among others, Färjestad, Calgary and Colorado.
