He told the club's official website: "I would play for Barnsley again in a heartbeat. I thoroughly enjoyed my time there and we did really well. "The supporters and their messages have been overwhelming, especially when you think I only played two matches for the club. Barnsley is a special place and I would like to thank everybody. At the moment I'm just concentrating on recovering. I have another hospital visit in a month and we will take it from there."
Wallwork made two starts for Barnsley in late November, playing the full 90 minutes in a 1-0 home win over Ipswich and a 2-0 victory against visiting Southend.
