The Owls are currently sixth in the Championship, though for how much longer remains to be seen.
Sheffield Wednesday's Jordan Rhodes has an attempt on goal
Despite dominating the match, Sheffield Wednesday left the pitch at Hillsborough following a 2-0 defeat to Reading knowing their play-off chances hang in the balance.
A series of fine Ali Al Habsi saves denied Wednesday a goal, and it appears now that if anyone is to fall out of the top six - be it for Fulham or anyone else - it will be the Owls.
The phrase 'doing a Derby' was coined after the 2014/15 season, when Derby County were top of the league by the end of February, but ended the season in eighth position - dropping out of the play-offs on the final day of the season.
While Wednesday's implosion isn't, and won't be, anywhere near as bad as Derby's that season, the cause for concern amongst the Wednesday fanbase is palpable, with a number of supporters suggesting that this has been coming.
Sheffield Wednesday players look dejected after the match
Carlos Carvalhal's side have two weeks to prepare for their next Championship fixture, which is a tricky Yorkshire derby away at Barnsley that could have huge implications on their play-off ambitions if Wednesday slip up.
With the Owls just a point ahead of seventh placed Fulham, it's a game they simply cannot afford to lose - or even draw - if they want to avoid future chokers being dubbed as 'doing a Wednesday'.
