Watford youngster Dennon Lewis has signed a three-year professional deal.
The 18-year-old, who has yet to make a first-team appearance for the Hornets, is a graduate of the club's academy.
"Hopefully I can progress into the first team and play in the Premier League," Lewis told the club website.
"Signing with any club, let alone a Premier League club, is amazing. Being able to play with these players at the level they are playing at is incredible," added Lewis.
