McCaw has not played a professional match since the All Blacks were beaten by England at Twickenham in December.
He played in an amateur club match last weekend and had been expected to return to top rugby from an eight-month sabbatical in New Zealand's Rugby Championships test against Australia on August 17.
McCaw had ruled out playing in this season's Super Rugby competition but has been hurried back because the Christchurch-based Crusaders are trying to end a five-year title drought.
Coach Todd Blackadder has made one change to his starting 15, with lock Luke Romano cleared to return in place of Tom Donnelly who drops out of the squad.
Luke Whitelock will cover lock from the bench.

Substitutes: 16 Ben Funnell, 17 Joe Moody, 18 Luke Whitelock, 19 Richie McCaw, 20 Willi Heinz, 21 Tyler Bleyendaal, 22 Adam Whitelock.
