Samoa will be hoping to secure a 2018 Rugby Sevens World Cup qualification berth at the final round of World Rugby Sevens Series event in London this weekend.
Action at Twickenham Stadium is due to begin tomorrow and conclude on Sunday (May 21).
The final spot at the 2018 Rugby Sevens World Cup in San Francisco in the US will go to either the Samoans or Russia, with the Pacific islanders 21 points ahead of their rivals.
Russia can draw level but would need to win the tournament to gain 22 series points, which would be their first ever victory.
New Zealand, England, Fiji, Kenya, South Africa, Wales, Australia, and France as well as the hosts have already qualified.
Canada, Argentina and Scotland also secured qualification last weekend in Paris.
The 11 other spots up for at the World Cup will be decided by regional competitions between June 2017 and April 2018.
Samoa have been drawn in Pool D with hosts England, Australia and Spain this weekend.
Pool A will see South Africa, the US, Wales and Kenya compete.
