Chelsea were booed off after they blew another lead at Stamford Bridge, with Wesley Fofana's red card and Zian Flemming's powerful header helping battling Burnley grab a precious 1-1 draw.
Liam Rosenior's Blues were in complete control, pushing for a second to add to Joao Pedro's early opener. But then their red-card problem struck again.
For an eighth time this season they were reduced to 10 when Fofana planted his studs into James Ward-Prowse's foot for a second yellow. Tosin was lucky not to follow him back to the dressing room for a shove on Flemming when he got the wrong side of the centre-back.
But Flemming would have his big moment - capitalising on non-existent marking to head home a 93rd-minute corner.
Burnley may have suffered a bad FA Cup exit to Mansfield last weekend but this draw, on the back of their comeback win at Crystal Palace last time out in the league, shows the second-bottom side are still fighting. Their gap to survival is now eight points.
Chelsea, though, were masters of their own downfall. After Sunderland and Leeds came from behind here earlier in the season, Burnley have completed the set for promoted sides battling back for rewards at Stamford Bridge. Crucial points Chelsea could count the cost of come the end of the season. They are up to fourth - but their fans are not impressed.
