Crusaders Assistant Coach, Jason Ryan is calling on New Zealand Rugby to remove their All Blacks rest protocols which are affecting New Zealand Super Rugby teams this season.

Ryan says the protocols require the All Blacks players to play no more than 180 minutes in the first three matches and this has caused fans to criticise New Zealand Rugby for the past two weeks and also teams are frustrated.

The Crusaders have eight All Blacks players this year, prompting coach Scott Robertson to tick off the first two weeks off for both Joe Moody and George Bridge.

When both players played against the Chiefs on Saturday night, it had been almost three and a half months since they last played.

Chiefs coach, Warren Gatland and Highlanders coach, Tony Brown have also criticised the protocols.

Ryan also confirmed the Crusaders were set to welcome back first-five eighth Richie Mo'unga against the Blues at 6.05pm this Friday.
