Ross McCormack has had surgery to remove five cysts from his jaw, and has been ruled out for the rest of the season, reports the ​Daily Mail.

The latest setback for McCormack comes after an achilles injury, and he is on loan at Nottingham Forest from Aston Villa.Villa signed him for £12.5m from Fulham in the summer, but the Scottish star needed an injection in his achilles and a three hour surgery to remove the cysts.

He has significant facial swelling, and has been advised not to train for a fortnight. Forest have been supportive of the striker, but, with his achilles needing a rest, McCormack feels that he has played his last game of the season. He scored on his Forest debut against Norwich.

McCormack said that: "It's been a freakish couple of weeks in what has been an abnormal season for me. Forest have been good with me. I wanted to help them but the doctors have advised that I avoid contact in training and rest up. I'm not used to seasons where I don't play a lot of games and don't get my goals. I desperately want to get back to that. The move to Villa did not start as planned but hopefully I can get myself sorted and come back in the summer nice and fresh."

The ex-Fulham goal scorer had only netted three times for Villa, after scoring 23 for the Cottagers last season. McCormack had a fallout with Villa boss Steve Bruce after he failed to report to training because his electric gates at his house were stuck, leading to Bruce to exile him from the first team squad.

It is rumoured that Villa will look to sell the Scot in the summer after his failed loan spell at Forest. The hitman will now sit out crucial games against Reading, QPR, and Ipswich as Nottingham Forest continue their battle to avoid relegation.
