Both exits are surprising in their own ways with Rotherham United and Steve Evans calling it quits after more than three years in which the Millers have moved from League Two into the Championship.
Rotherham actually moved off the foot of the division at the weekend when ex-Nottingham Forest man Matt Derbyshire netted in an impressive 2-0 victory at Birmingham City.
A much shorter time in charge has been ended at Brentford, meanwhile, with head coach Marinus Dijkhuizen having his ninth and final game at the helm in the weekend defeat by Sheffield Wednesday.
Lee Carsley steps up for the remainder of the season and will be in charge when Forest travel to Griffin Park on Saturday 21 November.
