The bookies still rank Boro as the favourites to earn promotion to the Premier League.
Aitor Karanka's side are in with a strong chance of going up but did get comprehensively beaten by Hull City recently.
Hull themselves follow shortly behind Middlesbrough, while Derby and Brighton are next in line.
QPR recently sacked Chris Ramsey and installed Neil Warnock as his temporary replacement.
The R's are now one of a number of Championship clubs seeking a new long-term manager, meaning promotion would be a considerable achievement for them.
Middlesbrough have looked strong all season long but started slower than many might have expected. Derby also started slowly and are now in the running once more.
Brighton have been the story of the season so far yet the coming few months will determine whether the Seagulls are in it for the long haul or not.
That sentiment applies to many, of course, with there not being too many points separating the top of the Championship and the rest of the division.
