Bury caretaker manager Richie Barker admitted his side had experienced a reality check as Wycombe dealt a severe blow to their title ambitions.
The Shakers, who secured promotion to League One on Easter Monday, could have moved to the League Two summit ahead of Chesterfield on goal difference with victory but went down to a 3-1 defeat.
Barker said: "It's hard because it's not what I wanted and I'm sure it's not what the fans or the players wanted."
He added: "Sometimes we just have to take stock and step back a little bit. We've come a long way in a short period of time but it's a bit of a rubbish end.
"It's important we go about the final game in the right way. If we don't do that we'll kick ourselves.
"There's a lot of disappointment there at the moment but it's not the end quite yet.
Wycombe are now favourites for the third automatic promotion spot, sitting a point ahead of fourth place Shrewsbury, who were 1-0 winners at Cheltenham and manager Gary Waddock hailed his side's best away performance of the season.
He said: "I thought we played really well. When you take into account we went a goal down, we didn't panic and got back into the game. The way and the manner we played second half was a credit to everybody at the club and the players have done extremely well.
"Without a doubt it was our best away performance of the season. We've done well on the road and got some really good results but to come here, perform like that and get the result was pleasing.
"They wanted to go for the title. They're an extremely good side and have done well this year to get promoted. The biggest thing is that promotion's in our own hands now. That's what we wanted, to go into the last game with destiny in our own hands."
