Nottingham Forest have come to life in the Premier League over the last few weeks with an impressive run of form that has seen them climb out of the relegation zone, however, a huge injury setback has now been revealed by a reliable source that will be troubling for Steve Cooper.

What's the latest?

The Telegraph's Midlands football reporter John Percy has confirmed that Dean Henderson will be out of action following a thigh injury sustained against Leicester City last weekend.

Percy tweeted:

"#nffc goalkeeper Dean Henderson set to miss 3-4 weeks with a thigh injury sustained in Leicester game on Sat. Wayne Hennessey expected to deputise but Forest may consider signing another goalkeeper."

Cooper will be frustrated

There is no doubt that the latest injury blow to Henderson will be frustrating for Cooper as the side have finally hit a consistent and positive run of form of late and the Manchester United loanee has been a key player in the team's rise up the table in recent weeks.

Although Forest have spent the majority of their campaign in the relegation zone, they are now 13th in the Premier League after picking up 10 points in their last five games, creating a five-point gap between themselves and the bottom three which is an incredibly impressive comeback ahead of the second half of the season.

The 26-year-old keeper is currently the fourth highest-rated player in the Forest squad and was integral in the club's progression to the FA Cup semi-finals last week when he saved two of penalties in the shoot-out against Wolverhampton Wanderers at the City Ground.

Not only that, Henderson ranks seventh for shots saved and ranks fourth for aerial challenges won in the entire Premier League this season so far, proving that he has been an outstanding performer for the Trentside team.

Cooper will now need to rely on Wales international Wayne Hennessey to cover for the talented keeper should the club not dip into the market this month to strengthen the position whilst they have the opportunity to do so.

Hennessey has conceded seven goals over his four appearances for the Tricky Trees since joining in the summer, however, in his two appearances in the FA Cup the Welshman did keep two clean sheets so the manager will be hoping he can rely on the keeper to retain the positive momentum when they face Bournemouth this weekend.

With that being said, it will be interesting to see how the powers at the City Ground deal with the loss of Henderson and whether they will take advantage of the January transfer window to bring in another keeper to cover over the upcoming fixtures.
