Brighton have overcome a missed a penalty and a disallowed goal to salvage a 1-1 draw with rivals Crystal Palace in the English Premier League.
A late own goal from Joachim Andersen helped the Seagulls snatch a point after Conor Gallagher's seventh goal of the season gave Palace an undeserved second-half lead.
But the Eagles were unable to snatch all three points in Sussex for the third successive season as Andersen inadvertently diverted the ball into his own net three minutes from time.
Seagulls midfielder Pascal Gross had seen a weak first-half spot-kick kept out by Jack Butland before Neal Maupay had a close-range strike ruled out for a foul on the Palace goalkeeper just moments later.
VAR was at the heart of the drama, with referee Robert Jones consulting the pitch-side monitor ahead of both decisions.
Butland was in inspired form to keep Patrick Vieira's visitors in the contest.
In addition to the maiden top-flight penalty save of his career, the former England international produced fine stops to deny Leandro Trossard and Jakub Moder, while the latter also struck the crossbar.
"In the second half we knew that if we kept defending well then that would frustrate them and we could create chances," Palace boss Patrick Vieira told Sky Sports.
"It is a positive result for us. We were disciplined today and we needed to be patient as well. We defended well as a team and we need this kind of maturity as a team."
The entertaining south-coast stalemate moved Brighton to eighth on goal difference, three places and four points above their opponents.
Brighton boss Potter told Sky Sports: "I have pride overall in terms of our performance - the first half especially.
"To recover from the setback of missing a penalty and to recover from the setback of going a goal behind is really pleasing.
"Overall I thought we were the better team and we deservedly got something from the game, which is pleasing for us."
