Former Everton youngster Femi Orenuga is currently on trial with League One side Crewe, scoring on his debut against Norton United.
The winger played 45 minutes against the non-league side in a game that also saw Matias Pogba, Brad Inman and Anthony Grant find the net in a 4-0 win.
Rotherham chairman Tony Stewart has backed his manager Steve Evans to take the Millers to the Premier League after handing him a new three-year contract.
The South Yorkshire club were struggling to get out of League Two before Evans' arrival from Crawley in April 2012, but the Scot has transformed their fortunes, leading them to back-to-back promotions in his first two full seasons at the helm.
The latest rise was achieved by beating Leyton Orient on penalties in the League One play-off final at Wembley on Sunday and Stewart has moved quickly to tie his man down until the summer of 2017.
