Hull striker Jonathan Parkin is a major doubt for the start of the new season after it emerged that he has broken a bone in his foot.
The 24-year-old picked up the injury in The Tigers' pre-season friendly against North Ferriby, but it was not immediately clear how much damage had been done.
He is now facing a race against time to be fit for Hull's opening Championship game of the season on August 5 against West Brom, although chairman Adam Pearson is confident he will recover quickly.
"Jon suffered the injury against North Ferriby and there is a chance he will miss the start of the season," Pearson confirmed.
"It is a non-weight bearing bone so hopefully not too serious."
Hull have had a torrid time with injuries over the past 12 months or so, and the situation does appear to be improving.
"After last season we were hoping for a bit more luck with injuries, but unfortunately that has not been the case so far," said Pearson.
New signing Sam Ricketts suffered a similar injury to Parkin in the friendly against Doncaster last week and also looks likely to miss the start of the new campaign.
"The extent of the injury was not discovered until about 48 hours after the Doncaster game," Pearson explained.
