Crusaders coach Scott Robertson has made five changes for Saturday's Super Rugby Aotearoa encounter against the Highlanders in Dunedin.
Kick-off is at 09:05 (SA time).
The tight five remains unchanged, while there are two changes in the loose trio. Cullen Grace underwent surgery on Tuesday for a fracture at the base of his right thumb, which sees Ethan Blackadder start in his place. The 22-year-old Tom Christie also earns a start this week, coming in for Billy Harmon at openside flanker.
In the backline, Bryn Hall and George Bridge will be rested, meaning Mitch Drummond starts at scrumhalf and Leicester Faingaanuku on the left wing.
The other change is a positional one, with Will Jordan moving to right wing to make way for vice-captain David Havili, who slots in at fullback.
Exciting Tasman back, Fetuli Paea, is set to become Crusader number 245, having been named on the bench for what will be his first Super Rugby appearance. Also included on the bench is Oli Jager, who was a late withdrawal from the side last week with a back complaint and is now fully fit to return to the match-day squad.
Following their successful return from injury to play club rugby last week, Andrew Makalio and Quinten Strange have both been named on the bench for the first time in Super Rugby Aotearoa.
The Crusaders are unbeaten in the competition, having beaten the Hurricanes 39-25 in Wellington and the Chiefs 18-13 in Christchurch.
