The former Leeds man is set to take charge of The Millers from Monday.
Redfearn has signed on to guide The Millers until 2018 and will be unveiled at a press conference at the New York Stadium on Monday.
The news may not be as breaking and special as that of Jurgen Klopp at Liverpool but in Yorkshire this is big news.
Redfearn is a local lad who had a dramatic season at Leeds United last term. He spent two periods in charge at Elland Road last season. He first took over from Dave Hockaday after he was sacked by Massimo Cellino and then again after Darko Milanic fell foul of the controversial Italian.
Redfearn brought through the younger players at the club and guided Leeds to survival in the Championship last term.
However his spell at the club also saw his assistant Steve Thompson removed from his job as assistant and clashes with the foreign contingent at the club. In the end his relationship with Cellino had deteriorated to the point that Redfearn had to leave Elland Road.
He will also be reunited with former player Aidy White at the club and will be hoping to follow in Steve Evans' footsteps and guide Rotherham to safety.
