Kenya and Uganda, who face off in the Elgon Cup on Saturday 26 May in Kampala dropped a position each, to 30 and 35 respectively, in the latest World Rugby Rankings released on Monday 21 May 2018.

Chile ended up third in Sudamerica 6 Nations competition after flattening Paraguay 97-0 in Santiago.
The win earned the side valuable points enough to improve to position 29 in place of Kenya who back down to 30. Last week Chile and Kenya both went a place up benefitting from South Korea's drop after a 21-30 loss to Hong Kong.
With Kenya and Uganda facing off before the next rankings release, Kenya has a chance of rising or Uganda can reduce the gap between them and their East Africa rivals.
Both Men's and Women's World Rugby Rankings are calculated using a 'Points Exchange' system, in which sides take points off each other based on the match result. Whatever one side gains, the other loses.
The exchanges are based on the match result, the relative strength of each team, and the margin of victory, and there is an allowance for home advantage.
