Brazil great Marta goes off in tears after red card

Brazil's all-time leading goalscorer Marta walked off the pitch in tears after being shown a straight red card during their 2-0 defeat by Spain in the Olympic women's football tournament.

Marta, who will retire from international football this year, was sent off for narrowly missing Olga Carmona's head with a dangerous high-footed tackle during the Group C match in Bordeaux.

Her hopes of appearing again in the tournament now rest on whether Brazil make it through their quarter-final tie against hosts France, after the Selecao advanced as one of the best third-placed sides.

Brazil were level when Marta was sent off just before half-time, with Spain, scoring in the 68th minute and then the 17th minute of second-half injury time - an extension prompted by multiple injury delays - to maintain their 100% record.

Marta, 38, won Olympic silver at Athens 2004 and Beijing 2008, losing to the United States on both occasions.

She is the all-time leading scorer in World Cups, men's or women's, with 17 goals in 23 appearances across six tournaments.

Marta, who is playing in her sixth Olympic Games, announced her intention to retire from international football this year in April

US continue fine form & Canada qualify

The United States maintained their perfect start to the competition with a 2-1 victory over Australia to top Group B and set up a meeting with Japan in the quarter-finals.

Goals either side of half-time by Trinity Rodman and substitute Korbin Albert put Emma Hayes' side firmly in control, although a late Alanna Kennedy effort ensured a nervy finale.

The US, who are record four-time gold medallists in the competition will face Japan in a repeat of the final from London 2012, at the Parc des Princes, Paris on Saturday at 14:00 BST.

Japan finished second behind Spain in Group C after beating Nigeria 3-1 in Nantes.

Reigning Olympic champions Canada also qualified for the knockout stage with a 1-0 win over Colombia, despite losing an appeal for a six-point deduction.

France topped Group A with a 2-1 victory over New Zealand.
