The NSW Waratahs’ Super Rugby campaign must continue without key forwards Will Skelton and Tolu Latu.

On Monday Latu was suspended for four weeks and Skelton for two for their lifting tackle on Crusaders second rower Sam Whitelock in Sydney last Saturday.

A SANZAR appeals committee on Thursday night confirmed the punishments, ruling the the players had failed to prove that the sanctions were manifestly excessive or wrong in principle.

Wallabies forward Skelton travelled to South Africa with the team on Tuesday while Latu stayed at home.

Uncapped Dave Porecki, who plays for Sydney club Manly, was added to the squad after Latu’s suspension was imposed.
