Samoa, wearing black armbands in memory of former under 20 flanker Faiva Tagatauli, who died this week following a head injury in a club game, produced the biggest upset when they beat England 12-10.

South Africa, who lie fifth in the series after two rounds had wins over Kenya, France and Scotland, to emerge from pool B unbeaten and which will ensure they overtake England in the overall standings.
