Gary Johnson's side fell behind to a goal from Darren Ambrose in the eighth minute at The Valley, where he coolly slotted the ball past Adriano Basso from 12 yards.

But centre-half McCombe - who had not scored all season until a fortnight ago - made it three goals in four games, rising unmarked to nod Lee Johnson's corner past goalkeeper Nicky Weaver in the 62nd minute.

The result means the Robins are three points clear of Watford, who climbed up to second place at the expense of Stoke with a 1-1 at home to Norwich.

The Hornets dominated a scrappy game and looked set to claim the win thanks to defender Danny Shittu's 11th-minute header.

But Norwich substitute Jamie Cureton hit a sensational long-distance strike nine minutes from time to give his side a share of the points.

West Brom striker Kevin Phillips headed home in the sixth minute of added time to give his side a 1-0 win at Sheffield Wednesday to remain in touch with the leaders.

The result means Wednesday, who had winger Jermaine Johnson sent off, remain in the relegation zone.

Plymouth moved into the play-off places by thrashing bottom side Colchester 4-1 at Home Park.

A Philip Ifil (11) own-goal gave Argyle the lead - before Jermaine Easter (57), Steven MacLean (60) and Gary Sawyer (68) put the home side in control. United striker Kevin Lisbie (64) netted a consolation for the visitors.

Ipswich slipped out of the play-off zone when they were held to a 1-1 draw by Sheffield United at Portman Road.

James Beattie gave the Blades the lead in the 32nd minute, but Alan Lee equalised for Jim Magilton's outfit in the 54th.

Hull remain in the chasing pack after a bad-tempered 2-0 win over Burnley at the KC Stadium, where four players were sent off.

On-loan Manchester United striker Fraizer Campbell put the Tigers ahead in the 14th minute, and Richard Garcia doubled the advantage in the 28th.

Caleb Folan and Jay-Jay Okocha were red-carded for the home side - and Steven Caldwell and Joey Gudjonsson were sent off for the visitors.

Jason Euell's 94th-minute header dented Wolves' play-off push as 10-man Southampton twice came from behind to earn a deserved point at Molineux.

Sylvan Ebanks-Blake (61) put the home side ahead with a powerful strike from the right side of the area, before Gregory Vignal (75) levelled from the penalty spot.

The Frenchman was sent off late on for two bookable offences, and the visitors looked set to pay the price when Ebanks-Blake (88) fired in his third goal in four days.

There was still time for one last twist, however, as Euell rose to meet Mario Licka's corner and powered a header into the top left corner.

Elsewhere, Crystal Palace's match with Cardiff finished goalless - while Darren Carter's 90th-minute strike gave struggling Preston a 1-0 win at Leicester.

Jamal Campbell-Ryce's equaliser just before half-time cancelled out Gary Taylor-Fletcher's 20th-minute opener as Barnsley drew 1-1 with Blackpool at Bloomfield Road.
