Recalling him might be an option. Dumbarton though?
Id maybe let him keep playing however, better for his development than being a back up here for the season?
Its so hard for a young keeper ever to break into a first team, there's no protection, when its your time to be involved there's nobody to save you, you have to be pretty special to get that trust.
Or prove yourself while away, id keep him out.
Don't think he's been recalled but more trying to save face - (that's about all he could save!) as hopefully been told not good enough and won't play again.
Another in long line of glorious goalkeeping disasters - won't be missed.
