Rory Kostjasyn (born 6 June 1987) is a former Ireland international rugby league footballer. He played in the National Rugby League for the Melbourne Storm and North Queensland Cowboys, with whom he was a member of their 2015 NRL premiership and 2016 World Club Challenge winning sides. An Ireland international and New South Wales Country representative, he played at hooker, but could also fill in at lock, and five-eighth. Kostjasyn is the current coach of the Newcastle Knights Intrust Super Premiership NSW team.
Kostjasyn was born in Sydney, New South Wales, Australia and grew up in Berkeley Vale on New South Wale's Central Coast. Of Russian and Irish descent, Kostjasyn's grandparents on his father's side are both from Russia.
He played his junior football for the Berkeley Vale Panthers, and was signed by the Sydney Roosters as a teenager, playing for their Jersey Flegg Cup side. While contracted to the Roosters, Kostjasyn played for their New South Wales Cup affiliate the Newtown Jets. After not playing first grade at the Roosters, he signed with the Melbourne Storm for the 2010 season.
Kostjasyn made his first-team début for the Melbourne Storm against Harlequins RL at the Twickenham Stoop in the World City Challenge, the Storm's warm-up match before the 2010 World Club Challenge. He played again a week later against the Leeds Rhinos from the bench in the World Club Challenge.
Training with the first grade squad over that summer earned Kostjasyn a spot in the club’s World Cup Challenge squad and a subsequent medal as part of the winning team. He was later signed by the club on a two-year-contract.
He then went on to make his National Rugby League début in the 2010 NRL season. He went on to play 7 games that season making his début in Round 1 of that season. He scored his first try for the club in Round 14 of the 2010 season.
In 2011, Kostjasyn was a more regular member of the Melbourne team, playing 12 matches, starting in three of them. Known for his versatility, played games at five-eighth, hooker and lock in 2011.
Kostjasyn played in 14 games in the 2012 NRL season, deputising for injured teammate Cooper Cronk in the halves at times. In Week One of the 2012 finals series against the South Sydney Rabbitohs, Kostjasyn made his first finals appearance. He was named 18th man for the Melbourne Storm in the 2012 Grand Final.
In 2013, Kostjasyn mainly played the hooker for the Cowboys, rotating with Ray Thompson. He made 20 appearances for North Queensland in 2013, including the semi final against the Cronulla Sharks, which he started at hooker.
In February, Kostjasyn played in the Cowboys' championship-winning Auckland Nines side. On 2 July, he re-signed with the North Queensland on another two-year-deal, keeping him with the Cowboys until 2016. He missed just one first grade game in 2014, due to broken ribs, starting 23 games at hooker.
On 21 February, Kostjasyn was a member of the Cowboys' World Club Challenge winning side, coming off the bench in the side's 38-4 victory over the Leeds Rhinos at Headingley Stadium. He played 26 games in his final season at the Cowboys and represented Country Origin for the first time in May. In October, he signed a 2-year contract with the Newcastle Knights starting in 2017.
During pre-season training with the Knights on 7 January, Kostjasyn suffered an accidental blow to his throat from Danny Levi. He was required to be sent immediately to the John Hunter Hospital after suffering a fracture in the Cricoid cartilage in his neck. He stayed overnight in hospital and was released on 8 January. On 25 July, he announced his retirement from rugby league due to breathing difficulties from the injury.
