Tottenham missed the chance to move into the Premier League top four after being held by West Ham at a rain-soaked London Stadium.
Brennan Johnson's tap-in put them ahead after five minutes, but they were pegged back when Kurt Zouma headed home from a corner.
Spurs were left frustrated in a game where both sides showed endeavour but lacked a cutting edge.
It meant Ange Postecoglou's side remain two points off Aston Villa in fourth.
West Ham, meanwhile, stay seventh as both Newcastle and Wolves failed to win and overhaul David Moyes' side in the Europa Conference League qualification place.
