Barnsley's Bobby Hassell headed home three minutes from time to deny Coca-Cola Championship leaders Newcastle an eighth successive victory.
Newcastle had taken the lead at Oakwell through top-scorer Kevin Nolan's sixth-minute effort but were pegged back when Emil Hallfredsson netted seven minutes into the second half. Marlon Harewood restored the table-toppers' lead with 12 minutes to play but Hassell ensured a draw for the Tykes when he nodded in from Adam Hamill's late corner.
Nottingham Forest continued their recent push to pick up a 1-0 win at Swansea, taking them to third in the standings. David McGoldrick was the scorer, volleying 10 minutes before the half-time break.
Sheffield Wednesday manager Brian Laws is likely to see the pressure surrounding his position as Owls boss reach fever pitch after his side capitulated 3-0 at fourth-placed Leicester. Steve Howard got the ball rolling early on for the Foxes before Andy King scored in either half to make it comfortable.
Welsh striker Freddy Eastwood scored a hat-trick to ensure Coventry finished on the right side of a five-goal thriller against Peterborough at the Ricoh Arena.
Eastwood netted twice in as many minutes in the first half before Craig Mackhail-Smith added a brace of his own in five second-half minutes. But Eastwood struck the winner just seconds after Posh levelled.
Roy Keane presided over a third win as Ipswich boss as goals from Jon Stead, Jack Colback and Gareth McAuley secured a 3-1 victory over Blackpool. Ian Evatt scored for the Tangerines, who had David Vaughan sent off late on.
Doncaster beat Bristol City 1-0, with Billy Sharp the scorer after 12 minutes, while Derby's Chris Porter scored the only goal against Watford.
