Substitute Jeffrey Schlupp cancelled out Ollie Watkins' goal as Crystal Palace earned a Premier League point at Aston Villa.
Schlupp had been on the pitch less than four minutes when he slotted in from Marc Guehi's knock-down following a corner with nine minutes remaining.
Watkins, who had been a doubt for the game after sustaining an ankle injury against Liverpool in midweek, beat Guehi to Lucas Digne's cross after 69 minutes with his first shot of the game.
Danny Ings twice went close inside the opening eight minutes for Villa, shooting wide following a darting run to the near post, and volleying over from Joachim Andersen's attempted clearance.
