Castleford Tigers full-back Blake Taaffe has been ruled out for the rest of the season after rupturing his anterior cruciate ligament on his Super League debut.
The 26-year-old Australian, who joined the Tigers from Canterbury Bulldogs on a three-year deal in the off-season, suffered the knee injury in Sunday's 26-16 home defeat by Wigan Warriors.
"I'm absolutely devastated for Blake. He has been a pivotal force behind the culture we are trying to build here at the club," head coach Ryan Carr told the club website.
"To know he finished the game with a torn ACL is a testament to how tough he is and how much care he has for his teammates and his club."
