Nottingham Forest are sweating over an injury to Cumbrian goalkeeper Dean Henderson.

Manager Steve Cooper says the Whitehaven star is having a scan on a muscle problem.

Henderson, who is on loan from Manchester United, suffered the injury when taking a kick in Forest's 2-0 win over Leicester City in Saturday's Premier League game.

The 25-year-old completed the game but Cooper admitted the injury was a concern.

"My first impression is, not good," Cooper said, speaking in NottinghamshireLive.

"But scans will tell more, with more clarity in the next day or two. We will have to see how that goes.

"It's a muscle injury, I think it's his thigh, but I'm not sure."

A lay-off for Henderson would be a blow for Forest after the former Carlisle United academy keeper's recent efforts.

The Cumbrian produced penalty shoot-out heroics last week to send the City Ground club into the Carabao Cup semi-finals.

They will take on Manchester United, with the keeper unable to play against his parent club.

Saturday was a sixth clean sheet of the season for Henderson, whose side are now 13th in the table.
