Cardiff City's wobbles at the top of the Championship continued as they were held to a 1-1 draw at home by injury-hit Derby County.
Indeed, it could have been worse for Malky Mackay's side as they fell behind to Conor Sammon's close-range finish with 15 minutes to go before Craig Noone headed an equaliser in the 82rd minute.
Watford moved into second place in the table after coming from behind to beat Sheffield Wednesday 2-1. Substitute Fernando Forestieri, who missed several good chances in the draw at Wolves on Friday, struck twice within 10 minutes in the second half after Michail Antonio had given the visitors the lead in the 19th minute following Watford goalkeeper Jonathan Bond's error.
Brighton in sixth were held to a 0-0 draw by bottom club Bristol City and lost striker Craig Mackail-Smith to a potentially serious Achilles tendon injury. However, Middlesbrough, who started the night in seventh, failed to build on Saturday's fine win over Cardiff as late goals from Alan Lee and Daniel Ward saw them crash to a 2-1 defeat at Huddersfield after Scott McDonald had given the visitors the lead in the 78th minute.
Boro have been overtaken by Nottingham Forest who continued their charge for a play-off place under Billy Davies but they made hard work of beating nine-man Ipswich at the City Ground, substitute Lewis McGugan's 84th-minute deflected goal clinching a 1-0 win. Earlier Lee Martin and Richard Stearman had been sent off for the visitors.
Blackpool finally scored under new manager Paul Ince, Kirk Broadfoot' s header from a Neal Eardley corner to earn a 1-1 draw at Birmingham ending a run of four goalless games.
Wolves scrambled clear of the bottom three with their first victory under Dean Saunders since he was appointed in January. David Edwards and Sylvan Ebanks-Blake secured a 2-0 win at fading Millwall, Ebanks-Blake scoring with a stunning overhead-kick.
