Hull FC head coach Tony Smith has confirmed that outside-back Connor Wynne has suffered an ankle injury during pre-season training.
Wynne, 22, is expected to miss up to seven weeks to recover.
The academy graduate has received shirt number 21 for the 2023 Super League season, having worn 23 previously. He has made 36 appearances for the club since his debut in 2019, scoring 14 tries.
Meanwhile, the new Hull boss has provided positive updates on forward pair Kane Evans and Andre Savelio.
The Super League outfit face Sheffield for their first pre-season friendly on Sunday at Olympic Legacy Park.
Full Hull injury update including Connor Wynne
Providing a full injury report, Smith said: “Nothing has changed too much in the last few weeks. Carlos (Tuimavave) is not quite ready for this one and Jake Trueman will still be unavailable for a number of weeks.
“Kane Evans is not far away. He’s getting really close, along with Andre Savelio.
“Everyone else is on schedule with their recoveries, as well. The only update since Christmas is that Connor Wynne has suffered an ankle injury.
“Connor got a twist of the ankle that is going to cause him five to six, maybe seven weeks of recuperation, which is not ideal for both parties. But these things happen when you get into contact in training.
“Jamie Shaul has also picked up a slight calf injury, although he’ll be back in running again next week. We’ve just had to take him out of running this week, which is a real shame for him because he’s been training terrifically.
“He’s been ripping it up and recording best-evers in tests, so we’ll be working to get him right. He’ll more than likely be good to go for the Wakefield game.”
