The goalkeeper joined the club on Friday and played in Saturday's 2-0 defeat to Bristol Rovers due to injuries to Owain Fon Williams and Lloyd Rigby.
Fon Williams had been called up for international duty with Wales last week but following a request to the Welsh FA he returned, only to pick up an injury in training.
The first-choice goalkeeper has since undergone a successful operation on a shoulder injury that had troubled him for the last six months and he will start his rehabilitation with Rodger Wylde next Monday along with Rigby.
He told the club's official website: "My shoulder got worse whilst I was away with Wales last week and it was decided that I should have the operation on Sunday.
"I'm back at home now and will be contacting Rodger shortly to talk about my rehab. The doctor said I'd be out from anything between three and eight weeks so you never know, I might be back before the end of the season."
