Under-23s winger Ryan Longman has joined Sky Bet League One AFC Wimbledon on a season-long loan.
The 19-year-old signed a new two-year contract on Monday, having been with the Seagulls since 2012.
Technical Director Dan Ashworth said, “This is a great opportunity for Ryan to test himself at a good level in the EFL. He will learn what is expected in that environment and it’s up to him to use this opportunity to kick on.
“Like all our players going out on loan, we will monitor his development during the season and we wish him all the best.”
