Swansea's perfect start to this Premier League season ended on Saturday as Steven Fletcher's first two goals for Sunderland saw the visitors to a 2-2 draw at the Liberty Stadium.
Scotland striker Fletcher, a £12 million signing from Wolves, scored twice in the first half, either side of Wayne Routledge's goal for Swansea -- who would have gone top of the table if they had won.
Michu scored his fourth goal in three games for the hosts to level the match at 2-2.
But the Swans then lost defender Chico Flores to a red card for a wild challenge having, before a goal was scored, seen Neil Taylor carried off on a stretcher after his leg buckled awkwardly after a challenge with Craig Gardner.
Great Britain left-back Taylor required prolonged treatment and was given oxygen as he received attention for an ankle injury.
Swansea capitalised on defensive errors in wins over QPR and West Ham, but a mistake of their own five minutes before the break saw Sunderland take the lead.
Ashley Williams stubbed his back pass into the ground and Fletcher ran in on goal to shoot low beyond Michel Vorm.
Swansea levelled as six minutes of stoppage time began. The in-form duo of Nathan Dyer and Routledge, linked again as the former's scooped pass allowed the latter to score with a volley.
But before the break Sebastian Larsson's free-kick found Fletcher, who tapped home at the back post to give Sunderland a half-time lead.
Michu came close to adding to his tally as his header into the ground from Johnathan de Guzman's cross bounced up and just over the bar.
But the same duo brought Swansea level in the 66th minute when Michu powered in a header from de Guzman's cross.
Swansea's comeback was halted when Chico was dismissed for a wild high-footed challenge that grazed substitute Louis Saha's head.
