Flanker Matt Todd’s excellent Super Rugby campaign with the Crusaders will go on hold for a month because of a calf injury.

The Crusaders must make do without flanker Matt Todd and centre Kieron Fonotia for a month after both suffered injuries in their Super Rugby win over the ACT Brumbies in Christchurch.

Todd tore his calf muscle in the second minute of the 40-20 win on Saturday while Fonotia suffered the recurrence of a hamstring injury.

Both are likely to miss the sixth-placed Crusaders’ next four games up until the June international window, with a possible return game being the tour match against England in Christchurch on June 17.

There is a ready-made replacement for the in-form Todd on the Crusaders openside flank after All Blacks captain Richie McCaw made an accomplished 80-minute return against the Brumbies after eight weeks out with a thumb injury.

Strapping wing Nemani Nadolo could shift in one spot to replace Fonotia or coach Todd Blackadder may turn to Tom Taylor or Rey Lee-Lo.

All Blacks utility Taylor is in doubt for their game against the Queensland Reds in Brisbane on Sunday after suffering a head knock against the Brumbies.
