Rovers are delighted to announce the return of Harry Chapman from Middlesbrough on a permanent deal.
The 21-year-old has put pen-to-paper on a two-and-a-half-year contract through to June 2021.
Chapman spent last season on loan at Ewood Park and quickly became a firm favourite with the Rovers players, staff and supporters.
The exciting winger made 16 appearances, scoring one goal - in a 2-0 victory at home to Rotherham United - before his season was cruelly cut short by a hamstring injury.
He returned to Ewood Park in May for the final day fixture against Oxford United, as Rovers celebrated an immediate return to the Championship.
It was the third season in succession that Chapman had helped a side secure promotion from the third tier.
The highly-rated youngster spent the 2016-17 season on loan at Sheffield United, where he scored four goals in 14 appearances, as the Blades lifted the League One title.
The previous season, Chapman impressed on loan at Barnsley, netting once in 14 outings, as the Tykes secured promotion to the Championship via the play-offs, as well as winning the Football League Trophy at Wembley.
An England youth international, Chapman was part of the England Under-20 squad that lifted the 2017 FIFA World Cup in South Korea.
The skilful starlet becomes Rovers' third signing of the January window, following the arrivals of Ben Brereton from Nottingham Forest and Brad Lyons from Coleraine.
