Chelsea collapsed to a 3-1 loss against Flamengo at the Club World Cup as Nicolas Jackson was shown a straight red card only four minutes after coming on as a substitute.
Enzo Maresca's side appeared to be in control of the game after Pedro Neto's breakaway opener in the first half but substitute Bruno Henrique's second-half leveller sparked an implosion.
Chelsea fell behind moments after the equaliser when former Manchester City defender Danilo punished more poor defending, and Jackson's red card came just three minutes later as he recklessly planted his studs on Ayrton Lucas' shin.
On the day he turned 24, and as he contends with competition for his place from new signing Liam Delap, Jackson's red card came only six weeks after he was sent off in against Newcastle in the Premier League.
Chelsea's afternoon went from bad to worse when Wallace Yan, another Flamengo substitute, added the Brazilian side's third goal to spark more wild celebrations from the vociferous Flamengo fans inside the Lincoln Financial Field in Philadelphia.
The result puts Flamengo three points clear of second-placed Chelsea in Group D, meaning they still have work to do to qualify for the knockout stages despite beating LAFC 2-0 in their opening game in Atlanta.
