Middlesbrough defender Dael Fry has signed a new five-year contract with the Premier League club and then joined Rotherham on a season-long loan deal.
Fry made his Boro debut in August last season, and has since made a further seven appearances for the club.
The Middlesbrough-born 19-year-old has won England caps at under-16, under-17 and under-19 level.
He could make his debut for the Millers when they host Bristol City in the Championship on 10 September.
