Barnsley's Rob Kozluk is losing his battle with a thigh injury and is unlikely to be fit to face his former club Sheffield United on Saturday.The 30-year-old defender, a free summer signing from Bramall Lane, is struggling to shake off the injury that has kept him out of the last six matches.

Tykes manager Simon Davey said: "Rob is a huge doubt for Saturday and we could rule him out now.

"He has not trained for three weeks, never mind play, and is looking very doubtful to return to the squad for Bramall Lane."

Kozluk, who has made a total of 12 appearances for Barnsley since signing in June, was hoping to step in for suspended full-back Dominik Werling and Davey now faces a selection dilemma for the South Yorkshire showdown.
