Nathan Wood has completed a permanent move to Swansea City.
The defender, 20, joins the Welsh side for an undisclosed fee in pursuit of regular first-team football.
Wood because Boro’s youngest-ever player when he made his his professional debut aged just 16 years and 75 days back in 2018.
The centre-back has since had loan spells with Crewe Alexandra and Hibernian, while he made two appearances - one in each domestic cup competition - for Boro last season.
The best wishes of all at MFC go to Nathan for the coming season and his future career.
