London Irish Wild Geese are nearly home and dry after a crucial win at Henley Hawks, but Barnstaple have dropped into the bottom three after their defeat to Worthing Raiders.

Henley Hawks 19-36 London Irish Wild Geese
London Irish Wild Geese are on the cusp of securing their place in National Two South for next season after a crucial win away at Henley Hawks.
