George Miller scored twice as League Two Doncaster Rovers came from behind to knock Championship side Hull City out of the EFL Cup.
Oscar Estupinan had put the Tigers in front from close range after only three minutes.
But Miller equalised after 15 minutes to bring the visitors level.
The Rovers striker then grabbed the winner just past the hour mark when he diverted a Harrison Biggins shot into the net via his head.
Hull made eight changes to their team from Saturday's last-gasp defeat to Norwich City in the Championship and one of those, Estupinan, scored his first goal of the season after Jason Lokilo had two efforts blocked in the area.
