Burton Albion will be without midfielder Sebastian Revan until the new year.
The 22-year-old, who joined on a season-long loan from Wrexham in August, has missed the Brewers' past two games and boss Gary Bowyer has revealed he is facing a lengthy period on the sidelines.

"I think he'll go back to Wrexham for a period as he's their player, so he's going to be missing for four to five, maybe six weeks."
Revan joins the Brewers' lengthening injury list with captain Udoka Godwin-Malife also missing Tuesday night's 1-0 League One defeat at Wigan after sustaining an ankle problem against Leyton Orient at the weekend.
"He's going to miss a month, that's for sure," said Bowyer. "It could go to two but that depends on how he heals, how hard he works in the gym and for us not to be pushing him and risking him even further."

"Charlie's operation went really well so that's good news because there was the possibility when they went in to repair [it] there could be a little more [damage] but it was exactly what was shown on the scan so he'll be (out for) a couple of months," added Bowyer.
"JJ had a flare-up of what he went off with the other month (hamstring) so that's not been good.
"It's amazing, you listen to people up and down the country and everyone seems to have injuries. There's so much data now but there seem, to me, to be more and more injuries."
