Leeds United missed the chance to return to the top of the Championship but snatched a point late on at Watford to extend their unbeaten league run to 14 games.
Watford produced perhaps their best half of the season as Vakoun Bayo and Emmanuel Dennis struck before the break, either side of a Crysencio Summerville stunner, to put them 2-1 ahead at half-time.
But substitute Mateo Joseph bundled in a leveller five minutes from time, seconds after coming off the bench, to extend Watford's winless streak at Vicarage Road to 10 matches.
Second-placed Leeds are a point behind new leaders Ipswich after conceding twice in a league game for the first time since Boxing Day.
