On 25 May 2016, Etheridge joined fellow League Two side Doncaster Rovers on a two-year deal.[6] Etheridge failed to impress and by mid January 2017 he was third choice keeper following the signing of Ian Lawlor. He was made available for transfer at the end of the season, though a training ground injury where he broke his ankle made this unlikely to happen.[7]
At the start of the 2020–21 season, Etheridge turned down a host of clubs to sign for home club Glapwell FC,[10] where he spent his junior years before joining the Derby County academy. His father, Neil, was the club's goalkeeper in the 1990s. Neil is still connected with the club as a groundskeeper.
