Huddersfield Town's Chelsea loanee Tino Anjorin has been ruled out by a serious ankle injury in training, head coach Mark Fotheringham has confirmed.
Although no timescale for his return has been given, the 21-year-old's immediate future with the Terriers is in doubt after undergoing surgery.
Anjorin, who also spent time on loan to Huddersfield last season, has two goals in nine games this term.
"We're really devastated for him," Fotheringham told BBC Radio Leeds.
"He'd worked really hard at the training camp in Spain. He'd put himself in the best shape physically, probably the best - and he would agree - he's been in his career so far.
