Ahmet Brkovic scored three goals in six minutes to help send Luton through at the expense of local rivals Stevenage.

A Kevin Nicholls own goal put Stevenage ahead early on before Tony Thorpe's powerful header pulled Luton level.

Richard Pacquette hit Boro's second before Brkovic made it 2-2 following Michael Leary's delivery.

He thumped home his second two minutes later and killed off the game with a cool left-foot finish moments later.

Richard Scott hit Boro's consolation.
