Managerial change
Following Rotherham's defeat to Oxford United on 17 March 2012, the club found themselves eight points from the play-off places in League Two. This prompted chairman Tony Stewart to sack Andy Scott two days later. Steve Evans was appointed as the new manager on a 3-year deal on 9 April.
