Barnsley dropped into the relegation zone of the Championship after a 3-2 defeat at Nottingham Forest.
Darius Henderson's late header sealed the points for Forest who had twice led but been pegged back by battling Barnsley.
Forest took the lead through Simon Cox after Mike Pollitt parried Jamie Mackie's initial effort, but Chris O'Grady equalised from the spot a minute later after David Perkins was brought down.
The hosts got back in front on the stroke of half-time when Kelvin Etuhu scored an own goal after Andy Reid's inswinging free-kick.
After the break, Barnsley scored a brilliant equaliser when Tomasz Cywka drilled in a free-kick from 35 yards. The ball flew into the top corner giving Karl Darlow no chance.
The Reds might have thought they worthy of a point but Henderson's late header ensured Forest's good start to the season continued while Barnsley are still searching for their first away point of the season.
