Brighton boss Chris Hughton accepts his side's late collapse against Leicester has increased the pressure on next weekend's clash with relegation-threatened Huddersfield.
Albion had the opportunity to significantly boost their survival hopes on Saturday but Glenn Murray missed a golden first-half chance and then saw a penalty saved before goals from Vicente Iborra and Jamie Vardy stole the points for the Foxes.
Hughton's Seagulls remain six points clear of danger with seven games to go following the 2-0 defeat.
They return to the Amex Stadium next Saturday for a meeting with David Wagner's 16th-placed Terriers - who are just three points behind them in the scrap for Premier League survival.
