Hull City boss Phil Brown accepts he could lose on-loan defender Paul McShane to Sunderland this month.
"Until I speak to Ricky Sbragia I can't answer questions about Paul McShane and his future," he said.
"It's their business if they do pull him back, that's the contract that we agreed as far as Paul McShane was concerned.
"It would disappointing if that was the case because I would like to keep Paul for the remainder of the season."
