Conference outfit Tamworth kept their FA Cup hopes alive as they held Championship Stoke to a goalless draw.
Lambs keeper Scott Bevan pulled off a string of fine saves to earn his side the replay a week on Tuesday.
Stoke dominated with Paul Gallagher's fierce shots testing Bevan in the first-half but they could not beat him.
In the closing stages, Tamworth boss Mark Cooper brought himself on only to see Eddie Anaclet and Jake Edwards denied by Stoke's resolute defence.
Tamworth had already accounted for League One Bournemouth and Hartlepool in their cup run and they gave Stoke a tough time at the Britannia Stadium.
Despite their stubborn approach, the Lambs rarely ventured into Stoke's half although Jake Edwards saw a 30-yard effort held by Steve Simonsen.
At the other end, Bevan did well to keep Stoke at bay and Adie Smith rescued his side after Luke Chadwick got behind the defence in the second half.
Mamady Sidibe wasted another good chance for the Potters when he fired straight at Bevan.
Stoke were simply out of luck - they even had a penalty appeal turned down for Matt Redmile's challenge on Sidibe - and had to settle for the draw and the replay.
