The 19-year-old striker worked his way through the Millers` academy structure after initially signing for the club as an under-16.
He was handed his first professional deal in December 2015 and has had several loan spells in non-League football since then.
His first was with Evo-Stik League South side Stocksbridge Park Steels and spent more time in the Evo-Stik with Grantham Town and Frickley Athletic.
He then stepped up to the National League North with Harrogate Town in January 2017 and then Worcester City and North Ferriby United, where he spent the early part of this season.
