Burnley boss Owen Coyle fears he could be without captain Stephen Caldwell for their first-ever Premier League fixture.
The Clarets take on Stoke City this weekend, but may have to do so without Caldwell after he picked up a groin strain on Wednesday.
The experienced stopper was withdrawn from Scotland's 4-0 thrashing by Norway shortly after half-time and Coyle fears he could now miss out this weekend.
"There's every chance that we'll probably be without our captain. Stephen Caldwell will miss the game on Saturday because of the injury he picked up," he told Sky Sports News.
"If that's the case that'll be a hammer blow. So I think the fixture was a bit untimely and it's certainly not helped us. We want to make the best of it.
"It's bizarre that they decided to put this fixture on the calendar prior to the opening of the Premier League season. It's disappointing if players are ruled out because of the fixture list."
Many are tipping Burnley to suffer a swift Championship return and Coyle believes their greatest inspiration comes from proving the doubters wrong.
"Everyone has opinions. It's opinions, it's not a personal thing. It's an opinion of football," he continued.
"The thing about football is you have the chance to prove people wrong. We want to do that, we want to prove we belong here.
"In order to do that we need to win games and that's the difficult part. It's a challenge we're up for and we're ready to retain our Premier League status."
