I believe that injury has been the issue, but that is based only on not playing at any level that I could find since leaving Swindon. Possibly, he wants his career outside of football to remain a private matter, if so that is his choice. Good luck, hopefully you are doing well, Tom.
I mean obviously Tom doesn’t have disclose his entire life publicly - no one does & he might absolutely be enjoying the anonymity.
Hell, he might even be glad to be out of football. He might have family business he’s part of. He might be a genius with masters degree.
Either way - I just hope it’s along those lines & not the other direction that a lot of ex pro’s go down when their career stalls / ends.
