Inverness have signed Irish midfielder Conor Pepper after a successful trial.
The 18-year-old joins from St Patrick's Athletic but had a previous spell at QPR.
Manager Terry Butcher said: "Conor has put pen to paper after showing up very promisingly in pre-season matches. He plays in the centre of midfield and has real potential."
He added: "Conor joins our first-team squad where he can be an asset as he's a lively performer."
Midfielder Liam Polworth has also been handed a professional contract, although he remains eligible for the under-20s.
