Butterfield has travelled with the squad to Austria as he steps up his injury return from a knee problem. Hughton told the club's official site the former Barnsley midfielder will benefit from the trip.
"It's vitally important to get away," he said. "That is why we brought Jacob with us because with the work he is doing he is not able to join in with everything the rest of the lads are doing.
"We could have left him at home, but he is better here. We have two of our physios, our masseur and all the medical staff over here so it is one where he can do all the work he needs and certain aspects where he can join in with the rest of the lads, which is a plus for him."
