Sunderland defeated Burnley 1-0 at the Stadium of Light to stop their opponents' winning start to the 2024-25 Championship season and maintain their own perfect record.
Both teams had won two games from two heading into Saturday's contest - Burnley scoring a combined nine goals - which was settled by Romaine Mundle's drive after 26 minutes.
Dan Neil was sent off late on for a second booking, but Burnley could not find a response as they tasted a first loss under manager Scott Parker.
Elsewhere in the late Championship kick-offs, Watford also made it nine points from nine as they recovered to beat Derby County 2-1.
Vakoun Bayo's superb strike cancelled out Ebou Adams' second-minute opener at Vicarage Road, before captain Moussa Sissoko grabbed a winner in the second half.
West Brom and Blackburn Rovers also remain unbeaten through three matches after beating Stoke City and Oxford United 2-1 respectively.
Karlan Grant and Josh Maja scored either side of Lewis Koumas's equaliser at the Bet365 Stadium, with both West Brom goals assisted by Tom Fellows.
