MATCH VERDICT AND PHOTO GALLERY: Another chance for Clarets in FA Cup replay
Tuesday night will be extra special if there is an action replay of Saturday's five-star entertainment.
Deeping Rangers should be full of confidence heading to Suffolk, knowing that they can create a series of chances to knock out another higher-ranked side in the Emirates FA Cup.
The Clarets came close to getting the job done at the Haydon Whitham Stadium - only for AFC Sudbury to hit back just four minutes after Scott Mooney's sensational strike.
Jordan Macleod - who had cancelled out the first-half opener by Sean Marks - set up Mooney to make it 2-1 but 17-year-old substitute Freddie King found the bottom corner of the net.
It was end-to-end stuff in a wide open game with so many opportunities.
In the early exchanges, Macleod was denied by Baris Altintop's tackle and Paul Walker's save before Dan Jarvis and Mooney also forced the keeper into action.
Altintop nodded over, Lewis Elsom pushed over Liam Bennett's drive and Ethan Mayhew couldn't convert at the far post.
Macleod and Mayhew went close again but the deadlock was broken in style as Marks headed home Ben Hunter's right-wing cross.
Marks missed the target instead of doubling the advantage then Mooney was kept out by Walker.
Jarvis had three more opportunities - the best one coming from Dan Banister's cross when the ball flicked off his head beyond the far post.
Dan Flack was next to test Walker who was protected by Joe Grimwood's brilliant block from Macleod.
Elsom made stops from Tom Maycock and Marks who also wasted a golden chance from close range after Banister nodded off the line.
Macleod's flick into space was coolly finished off to get Deeping back on level terms then two further efforts were diverted to safety.
Flack's burst was halted at the edge of the penalty box and Macleod rolled the free-kick to Mooney who blasted into the top corner.
But a replay is required thanks to King's 20-yard drive past Elsom.
