Experienced hooker Keven Mealamu will return to the Blues as they head into their repeat clash with the test-cap heavy Crusaders.
Mealamu had calf trouble in his comeback start against the Stormers and was spelled last week but is set to go on Saturday against the competition benchmarks. His appearance should help some of the scrum difficulties though the lineouts may be a tougher assignment. The Blues battled in both areas against the Rebels.
"If you look at all our games they are areas we need to continue to improve on," coach John Kirwan said. "The Crusaders are the best at it, they have the best lineout and the best scrum so we have to be on our game.
"How we deal with their forwards will be a huge part of the game. They have an All Black pack and we are the underdogs."
Kieran Read is expected to return from his foot injury to lead a Crusaders pack who have only Matt Todd without test experience. Tack on a quartet of backs with All Black credentials and the breadth of the Blues' task grows.
