Hull KR forward James Greenwood will not play again in 2019 after suffering a ruptured anterior cruciate knee ligament.
The 27-year-old sustained the injury just minutes after his introduction as a substitute in Sunday’s win at Wakefield Trinity.
Greenwood, who is out of contract at the end of the season, will undergo surgery in the coming weeks.
A Hull KR club spokesperson said: “The club can confirm that James Greenwood has undergone cans following an injury sustained in last weekend’s game against Wakefield Trinity.
“The second-rower was helped from the field and did not return to action during the round five tie.
“Scans have confirmed that he has ruptured his anterior cruciate ligament and will have surgery in the coming weeks. He is not expected to feature again in 2019.”
The Robins have also confirmed that forward Ryan Lannon will be out for 10 weeks following ankle surgery.
