Carlisle United loan star Fin Back says he has undergone successful surgery in Finland.

The Nottingham Forest player flew out for a procedure on his injured hamstring this week.

And Back revealed there were mixed emotions as he reflected on the situation.

In a post on Twitter, 20-year-old Back wrote: "Devastated - but unbelievably thankful for a very successful surgery from Dr. Lasse Lempainen and his team!"

Back, who is on a season-long loan with the Blues, is set to be out for about three or four months.

United boss Paul Simpson, speaking after Back's operation on Wednesday, said it is currently unclear whether he will remain on Carlisle's books or whether Forest will recall him in January due to his injury situation.

"We will have the conversations with Forest now that this surgery has taken place just to see exactly what they want to do with him," Simpson said.

"It all depends on what Forest decide, Forest may want to keep him back with them and they may want to recall him, I don't really know at this moment in time.

"It's more about getting him sorted with the surgery and starting his recovery and making sure everything's right for Fin to continue playing to the level that he did while he was with us."

Back has made 18 appearances in an impressive spell with the Blues this season.
