NIGEL Clough says the extent of Liam Boyce's injury will be more clearer next week when the forward goes for a scan.
The Brewers striker was stretchered off the pitch on 33 minutes after an incident off the ball.
"We will know a bit more on Monday after he has a scan," said Clough.
He added: "It was innocuous he just put his foot down and felt something in his knee. There's no point speculating until we find out more on Monday."
