#Rio2016: Nigeria and Portugal Progress, Brazil Held Again

Nigeria and Portugal became the first teams to qualify for the Olympic men's football tournament quarter-finals, while hosts Brazil were held again. 

The 2008 runners-up Nigeria backed up their thrilling 5-4 win over Japan with a 1-0 victory against Group B opponents Sweden, courtesy of Sadiq Umar's first-half goal. 

Portugal, who defeated Argentina in their Rio 2016 opener, made it two wins from two in Group D on Sunday with a 2-1 come-from-behind triumph against Honduras. 

Neymar's Brazil are still without a goal from their opening two Group A games of the tournament, held to another 0-0 draw, this time by Iraq.

Denmark boosted their chances of progression to the next round with a tense 1-0 win against South Africa, while Argentina got off the mark in Group D with a 2-1 victory over Algeria. 

Germany scored late through Serge Gnabry to salvage a 3-3 draw with South Korea in Group C, and Japan battled from two goals down to secure a 2-2 draw against Group B rivals Colombia.

Meanwhile, Fiji scored their first ever Olympic goal in their Group C clash with Mexico, but despite leading at half-time went down 5-1 to the defending champions.
