Sean Dyche fears that the knee injury sustained by Robbie Brady at Leicester could be a serious one.
The Clarets winger was in clear distress after over-running the ball and sliding into Harry Maguire on the half hour mark of the 1-0 defeat at the King Power Stadium.
Brady was stretchered off and rushed to hospital to be assessed – and Dyche later admitted he feared the worst.
“It looks more serious than not serious to me; that’s all I can say,” said the Burnley boss.
“He’s gone off to hospital, so we need to find out more before I can give the full facts.
“It’s a blow because Robbie has been excellent lately. Some of his deliveries today were excellent and he’s settled into the team nicely.
“He’s a good character in the group and he’s been building with his performances.
“Today he started fantastically well, so it’s a real knock for him and us and hopefully we’ll find out more details soon.
“But we’ve had knocks like this before, so we’ll rethink things and move forwards.”
The Clarets were Leicester’s equal in a productive first half, following a disastrous start when Demarai Gray slotted the Foxes ahead inside six minutes.
“Overall, I was quite pleased, particularly with the first half, when we were very productive and quite dominant,” added Dyche.
“We responded really well from a poor goal, from our point of view and it’s not easy to come away in the Premier League and have as much play as we did.]
“We took the game on and we were productive and arguably could have come in one each.
“We didn’t and that played into their favour in the second half. They thrive on the game it became in the second half because they love to play on the counter.
“But I was so pleased with the physicality because that was virtually the same group playing three games in six days.
“The will and desire to keep going all the way down the game and keep creating chances was there for all to see, so I’m pleased with many things and just not the result.”
