New Leeds prop Andy Yates has been ruled out for six months after rupturing his Achilles just four weeks into his career with the club.
Yates, 23, joined from Hunslet ahead of the 2014 season but now faces a lengthy spell on the sidelines after an operation earlier this week.
Head Coach Brian McDermott said: “We are all desperately disappointed for Andy, especially at the start of his time at the club.
“He is in the best possible hands here at the Rhinos and I am sure this will just be a minor set back for him given the determination he has already shown to succeed.”
Yates came through the youth system at hometown club St Helens, before moving on to Hunslet, where he made 27 appearances last season.
