Hull full-back Jake Connor will go for x-rays this weekend after suffering an injury playing for the Combined Nations All Stars in their win over England.
Connor, 26, played against Shaun Wane’s side having been snubbed for selection despite his form in Super League this season.
There are fears that he may have sustained a broken jaw.
All Stars coach Tim Sheens said: “I apologise to (Hull coach) Brett Hodgson if I send him back in pieces.
“The doctor thought it was broken but he went back out for the second half. He wanted to finish the match but we took him off because we didn’t want to do it any further damage.
“I hope it’s nothing more than a small fracture – that will be a bit of a wait.”
Connor appeared to take a knock trying to stop Liam Farrell scoring England’s first try of the evening, but he came back to play a crucial part in the All Stars victory.
He was also at the centre of some controversy in the second half, when the All Stars were awarded a try by the video referee despite suggestions of a knock on by Connor.
Wigan forward John Bateman went off with an ankle injury, while Leeds three-quarter Ash Handley didn’t return after a head knock.
