Leeds United moved back into second place in the Championship with a 1-0 win over Sheffield Wednesday on Saturday.
Sheffield United, who started the day third, were held to a 1-1 draw by Millwall at Bramall Lane thanks to a 95th-minute equaliser from Jake Cooper.
That result was enough to move them second on goal difference, but Leeds moved back above them and established a three-point gap to the chasing pack thanks to a second-half goal from Jack Harrison.
Keiren Westwood kept Marcelo Bielsa's side at bay for the first 65 minutes with some fine goalkeeping, with particularly impressive saves to deny Tyler Roberts.
