Johnston leaves Wasps

Johnston was injured with Samoa during the build-up to the World Cup and subsequent injuries mean he hasn't been able to train fully or play a first team game during his five months with Wasps.

Wasps' Director of Rugby Dai Young said: "It is unfortunate that James has not been able to train regularly since joining the club, as we were really looking forward to seeing the impact he could make in a Wasps' shirt. Unfortunately for both parties, this couldn't happen and he leaves with our very best wishes for his next steps."
