Hull winger Matty Dawson-Jones has suffered a season-ending knee injury just one game into the 2019 campaign.
Dawson-Jones, who joined the Black and Whites in the close season from Leigh and scored on his debut in the Hull derby, suffered an anterior cruciate ligament injury in training.
Hull coach Radford said: "Matty is done for the year. I had a really tough conversation today and I really feel for him.
"He needs to keep his head up, get his rehab right, and he'll come back stronger."
