League One newcomers Leyton Orient have signed Middlesbrough goalkeeper Sol Brynn on a season-long loan deal.
The 22-year-old spent last season on loan at Swindon Town, making 49 appearances in all competitions for the League Two club.
Brynn, who is yet to make his senior debut for Boro, has also had stints with Darlington and Scottish side Queen of the South.
He becomes Orient's sixth signing of the summer transfer window.
"We've been chasing him for a while, and for him to want to come to us speaks volumes about what we're doing here," O's goalkeeping coach Simon Royce told the club website.
