Barnsley manager Mark Robins has not ruled out adding further to his squad when the loan window reopens next week.
Robins has made nine new signings since the end of last season, but although there was no activity at Oakwell on transfer deadline day, it was not for a lack of trying.
Robins told the Sheffield Star: "Unfortunately the players I wanted to bring in are not available at the moment.
"I've spoken to a number of different people about the players that I'm looking at, but at the moment there's nothing doing.
"That's not to say that won't change and the loan window reopens next week."
