The top six in the Championship has remained at status quo for weeks with no club making a big surge into the top six until this past week.
The club breaking into the top six is Millwall, who have not lost since September 22nd.
With a 1-0 win over the Wolves on Tuesday, the Lions solidified their spot in the promotion race by jumping into fifth place in the table.
The London-based club have won their last four matches and are in the midst of a 12-match unbeaten run that started with an away draw at Burnley on September 29th.
Manager Kenny Jackett has gotten the most out of his squad in the last month with wins over Derby County, Leeds United and Blackburn to add to Tuesday's road triumph at the Molineux Stadium.
By taking the maximum 12 points from their last four matches, Millwall now sit in fifth place with 32 points ahead of their home match on Saturday with Charlton Athletic at The Den.
As for how the rest of the promotion contenders fared during midweek play in the Championship, Cardiff City and Crystal Palace stayed in the top two after both clubs drew on the road on Tuesday.
Cardiff's trip to Derby County resulted in a 1-1 draw with the hosts equalizing in the second half to deny the Bluebirds' attempt at becoming the first club to reach 40 points this season.
The draw puts Cardiff at 38 points, one point ahead of Palace who played to a 0-0 draw with sixth-place Hull City.
Middlesbrough gained ground on the top two with a 3-0 win at home over Huddersfield Town.
Boro received two goals from Scott McDonald in the win at the Riverside Stadium that saw the club jump over Leicester City into third place.
Leicester were unsuccessful in their visit to Elland Road as they fell 1-0 to Leeds United.
