Wolves extended their lead at the top of the Sky Bet Championship table to eight points after Cardiff failed to capitalise on their 2-2 draw at Millwall.
Nuno Espirito Santo's league leaders were forced to settle for a point at The Den as Millwall defender Jake Cooper headed home a second-half equaliser in a pulsating clash.
Lee Gregory had put the Lions in front in the 17th minute but Diogo Jota levelled and Romain Saiss then handed the visitors the lead after 56 minutes.
Despite the slip-up in the early kick-off, Wolves still increased their unbeaten run to 10 games and the point proved to be valuable due to Cardiff's 4-2 defeat at home to Fulham.
