O'Regan agreed to terms on a one-year deal with KHL club Kunlun Red Star on Monday.
O'Regan last played in the NHL back in 2021-22, when he was with the Ducks before spending all of the 2023-24 campaign playing in Sweden. At this point, the 30-year-old center will likely play out his career overseas, eventually retiring having played in 30 NHL contests in which he generated one goal and five assists.
