The injury ravaged past few seasons for Blues lock Ali Williams hit another road bump yesterday when he damaged a hamstring and headed for a month on the sidelines.

Williams was into the fourth game on his Super 15 comeback when he pulled up lame during his side's messy 22 all draw against the Force in Perth.

The Blues were not as divided in their opinions about their deadlock against the Force.

This Friday, the Chiefs start the Super 15 action with a home game against the undefeated Sharks at 6.35pm while the Crusaders travel to Dunedin for the early Saturday game at 4.30pm against the Highlanders before the Blues host the Hurricanes at 6.35pm.
