The Blues Super Rugby bye week seems to have the opposite of its intended effect.

Several players will be unavailable for Saturday's match against the Waratahs.

Forward Josh Bekhuis is thought to be out for a week while halfback Bryn Hall is unavailable after breaking his foot in club rugby.

Blues assistant coach Glenn Moore said they have tried to keep the physicality high at training and that's just part of it.

Patrick Tuipulotu and Charlie Faumuina look to be the rested All Blacks this weekend, taking an obvious lighter load at training.

The Blues will face the Waratahs at 8.40pm Saturday.
