Mark Robins admits that Barnsley have a 'bit of a problem' after confirming that defender Rob Kozluk is facing a fortnight out with a knee injury.
The full-back was forced off in Tuesday's 1-0 victory over Leicester and was replaced by Darren Moore in only the 17th minute.
Kozluk is now expected to be unavailable for around 14 days and, with Bobby Hassell also out of action, Robins hopes he has sufficient strength in depth in his squad.
The Tykes boss said: "Rob came off injured in the first half after jarring his knee.
"He will probably be out for a couple of weeks and that does give us a bit of a problem as we will be missing Bobby Hassell as well, but I'm confident we have enough in the squad to cope."
Meanwhile, striker Daniel Bogdanovic should be fit to face Reading this weekend following his recovery from a knee problem.
