The 22-year-old, who spent last term on loan at Accrington Stanley, has put pen to paper on a new deal with the Magpies – and linked up with the Millers for the coming campaign.

Gateshead-born Barlaser’s three Newcastle appearances came in FA Cup ties against Birmingham City and Oxford United in January 2017 and a Carabao Cup clash with Nottingham Forest in August 2017, before he made four outings on loan at Crewe Alexandra during the second half of 2017/18.

He impressed during his spell with Accy last season, making 39 appearances and netting three goals – including his first Football League strike, which came against Southend United at the Wham Stadium.

Barlaser becomes Rotherham manager Paul Warne’s sixth addition of the summer, and will remain at the New York Stadium until the close of the League One season in May 2020.
