Lee Hodson has signed a one-year deal at MK Dons after leaving Watford on a free transfer.
The Northern Ireland full-back who came through the Hornet’s youth system had one year left on his contract at Vicarage Road.
Hodson who is still only 21-years-old already has League One experience after spending most of last season on loan at Brentford.
“Lee fits into our transfer policy – he’s young and ambitious but has the experience of over 70 Championship starts,” said Manager Karl Robinson.
“He already knows League One from his spell at Brentford last season and I believe he will add great competition for places in our defence.”
