Championship wrap: O'Neill earns first Forest win
Martin O'Neill registered his first win as Nottingham Forest manager as Leeds United moved three points clear at the top of the Championship.
Several second-tier sides were in FA Cup action, but there were still some big results in the league, with Leeds returning to winning ways while Forest and Blackburn Rovers kept up the presser on the top six.
Norwich City and Sheffield United battled to a draw, losing pace behind Leeds, while Aston Villa defeated struggling Ipswich Town.
Stoke City had beaten Leeds last week, but its difficult season continued with a humbling home reverse at the hands of Preston North End.
Having lost last week, Leeds needed to show a response and its trip to Rotherham United did not start well, trailing to Semi Ajayi's opener for the hosts at the break.
But Mateusz Klich came up with a response following the restart, netting after 51 minutes to set up a tense finale. The same man then delivered to complete a turnaround, striking the winner four minutes from time.
Marcelo Bielsa's mood would have improved further upon seeing the result at Carrow Road, where Billy Sharp twice cancelled out Norwich goals as Sheffield United earned a 2-2 draw.
Leeds now holds a three-point advantage over second-placed Norwich City, with the Blades a further three points back after leapfrogging West Bromwich Albion.
Forest's first home match under former favourite O'Neill had underwhelmed, with Bristol City claiming a 1-0 win at the City Ground last time out.
But the Reds' fortunes improved in this clash. Despite registering just three shots on target against Wigan Athletic, O'Neill's men ran out 3-1 winners. Joe Lolley, Matty Cash and Adlene Guedioura were on target.
Although Forest climbed the table with victory, it remains below Blackburn after Tony Mowbray's side sealed an impressive 3-0 victory against Hull City.
Villa is also in the play-off picture after a 2-1 defeat of lowly Ipswich. Tammy Abraham continued his outstanding form with a brace.
Stoke would have hoped that its fortunes had turned with the arrival of Nathan Jones and a win against Leeds last week, but a wretched campaign was punctuated with another dismal defeat here.
Preston clinched a 2-0 win at Stoke with goals through Alan Browne and Brad Potts.
A side plying their trade in the Premier League just 12 months ago remains 15th in the Championship, with just one win in eight across all competitions.
