West Ham United were forced to settle for a 3-3 draw against Brighton & Hove Albion after they saw a two-goal lead slip through their grasp in the final 15 minutes at London Stadium.
The Hammers looked on course for all three points when Robert Snodgrass' double, added to Issa Diop's opener, had them 3-1 up approaching the hour.
However, Brighton came back at the hosts in the closing stages, pulling one back through Pascal Gross before a Video Assistant Referee decision ruled that Glenn Murray had not used his hand to control Davy Propper's cross before sweeping home.
