The extra workload may be starting to catch up on injury prone Crusaders second five Sonny Bill Williams.

Williams has been ruled out of the Crusaders match against the Hurricanes this weekend, after taking a hit to his hip against the Blues.

Assistant coach Daryl Gibson says the extra strain he's put on his body may be starting to take it's toll.

Gibson says combined with his boxing it's a huge workload Williams has put his body under and at times you're going to get injuries at the wrong end of the season.

Williams has fought two professional heavyweight boxing fight's this Super Rugby season.
