Sheffield United boss Nigel Clough has played down fears surrounding forward Chris O'Grady's fitness.
The 28-year-old, who is on loan from Brighton & Hove Albion, was forced off with a calf problem during United's defeat to MK Dons on Tuesday.
O'Grady is due to return to his parent club in January, though Clough has suggested that the deal could be made permanent.
"Chris was brought off as a precaution," Clough told the club's official website. "He just felt his calf tighten up and we would have been silly to risk him at this stage."
The Blades are in FA Cup action on Saturday when they host Plymouth Argyle in the second round.
