Sunday not only marks a huge final day clash for Wednesday, but it also marks the end of an era for the Owls' club captain, Lee Bullen.
Bullen will make the trip to Hillsborough for the final time as a Wednesday player on a Sunday and, whether he plays himself or not, he'll be looking to end his eventful stay at S6 by helping to keep the Owls' in the Championship with victory over Norwich City.
The Scotsman has become somewhat of a cult hero with Wednesday fans after becoming the most recent man to lift a trophy in the famous blue and white, and going on play in all eleven positions for Wednesday during his time at S6.
Nobody will forget that picture of Bully sitting in the changing rooms at Cardiff, empty cans of lager around him, a look of huge relief on his face, after he helped guide Wednesday fans to one of their best days out in recent history with the League One Play-Off Final victory over Hartlepool in 2005.
Nor will they forget Bully's performance at Millwall the following season, which summed up his commitment and determination to the club, as he replaced the injured David Lucas in the Wednesday goal for the whole of the second half at The Den, and went on to keep a clean sheet for the Owls in a vital match which all-but saw them secure their Championship status against their relegation rivals.
His appearance between the sticks saw him feature in all eleven positions for the club since his arrival - quite an achievement - and he went on to bag the Wash & Go 'Good Sport' award at the inaugural Football League awards dinner the same season.
And Bully told the Sheffield Star that his time at Wednesday has been his most enjoyable in his professional football career, despite the fact that he's also played in sunnier climates of Australia, China and Greece.
'This year aside, I'm really proud to have played a part in the club's progression over the last few seasons,' he said.
'We won promotion in my first year, then stayed up and only just missed out on the play-offs last season. But the stand-out moment for me, though, was leading out the team at Cardiff in the Play-off final.
'What a great honour. The atmosphere was electric thanks to the Wednesday fans - they really are tremendous - and, of course, winning promotion topped off the day.'
Bully's ability has been called in to question this season with a number of mistakes at the back, most recently in the 3-1 victory at Leicester City, but his time at S6 in all has been a big success, not bad for a 37-year-old (sorry Bully!).
But he's been 'Mr Sheffield Wednesday' since his arrival at Hillsborough, when Chris Turner brought him to the club on a free transfer from Dunfermline in June 2004, representing the Owls off the pitch as well as on it, including having his very own show on BBC Radio Sheffield.
So what next for the Scotsman now his days at S6 are over? A move in to the media? A coaching role? I'd certainly like to see Bully remain at S6 in some way, shape or form, but it looks like we'll have to wait a while for that at least, because he still wants to carry on his playing days for a little longer at least.
'There could be a chance of moving to Scotland but there has also been some interest from teams in England,' he continued.
'I've done my coaching badges up to the A licence and almost completed my media course at Stafford University.
'I'm trying to cover as many bases as possible and hopefully that will allow me to stay in the game in some capacity. Ideally it would be in coaching. I've been doing some work with the U-15s and U16s at Wednesday which I've really enjoyed.'
The Owls' very own Captain Marvel has featured 108 times in the league for Wednesday during his stay at S6, with further performances coming in the FA Cup, in which he scored against Manchester City in the Third Round Replay two years ago, and League Cup.
And I have no doubts the Edinburgh-born player will get a superb send-off from the Wednesday faithful in their final match of the season this weekend, and what a more fitting way than a full house at Hillsborough, and the biggest attendance in years to see the Scotsman on his way.
Cheers, Bully, and good luck in the future from all at Vital Sheffield Wednesday!
