Invicta Dynamos pulled off a shock result at Silver Blades on Sunday.
They became the first National League side to beat an EPL side in the English Challenge Cup.
The Mos had lost their opening five games in the tournament but beat the Brackley Bees 6-4 to claim their first scalp.
Kevin Parrish’s men had gone into the game buoyed by an 8-4 win over Oxford City Stars the day before.
Goals in the ENIHL Division 1 South win were scored by Steve Osman, Andy Smith, Harrison Lillis, Juraj Huska (2), Frankie Harvey (2), Anthony Leone.
On Sunday, early goals from Smith and Huska set them on their way against the Bess.
Bracknell pulled one back before the end of the first period and levelled on 32:52, which is how it stayed going into the final session.
Callum Fowler struck to make it 3-2 early on in the third period and Billy Phillips smashed home a fourth.
Smith slotted home a fifth but a double from Bracknell pulled it back to 5-4 before another Smith effort put the win in the bag for the Mos.
