Young defender Neil Austin is set to return to full training after recovering from a foot injury sustained against Swindon on Saturday.
A precautionary X-ray revealed Austin had not suffered a fracture as feared.
Tykes physio David Moore told the club's official website: "Neil trained with me and did well. He should be fine and will go back in with the full squad."
With Chris Morgan suspended for the next two matches, Austin is almost certain to play against Cardiff on Saturday.
