The club are delighted to announce the signing of 21-year-old full back Josh Doherty on a one-year-deal with the option of an extra year.
The Northern Ireland youth international has appeared at U17, U19 and U21 levels for his country.
The Watford academy product, who played under our Head Coach Harry Kewell during his time in Hertfordshire, signed his first scholarship forms with the Hornets in 2012, before making his senior debut for the club in 2014 against Huddersfield Town, signing his first professional contract 11 days later.
In the summer of 2016 the defender joined Leyton Orient, before moving on to Altrincham on a month’s loan.
"We're really happy to have Josh on board," Harry said.
"He's someone I know well from my time at Watford, he's young, hungry and has both international and domestic experience - so he's a good addition to our squad."
