Tom Clarke's late winner handed Preston a 1-0 victory over Lancashire rivals Blackpool in a tense Capital One Cup first-round clash at Deepdale.
Clarke's 87th-minute close-range header from Lee Holmes' free-kick sent the Sky Bet League One side through and prompted a pitch invasion at the end of the match.
Tom Ince could have put Blackpool ahead when he found himself through on goal but his 18th-minute shot from just inside the area was off-target.
Angel Martinez went agonisingly close for Blackpool in the 50th minute after his header from Kirk Broadfoot's cross went inches wide.
Iain Hume then nearly put Preston ahead with his 63rd-minute shot that Matt Gilks did well to push around his post.
Michael Chopra had a golden chance to give Blackpool the lead but his 72nd-minute header bounced into the pitch and over the bar.
The Seasiders pushed again and Bobby Grant's corner found Broadfoot but the defender headed over and, with Clarke capitalising moments later, the Championship side crashed out.
