"If we get him good minutes under the belt this week, he'll be starting to really hit his straps," Ryan said.
"Getting that confidence back, and physicality - being tackled, making tackles, mauling and that sort of thing - it takes its time, but he's an athlete and a world-class player. He's done a lot of work on and off the field; he won't be far away from full straps at all."
The Crusaders will meet a Sharks side with nothing to lose and everything to gain on Saturday night. Sneaking into the playoffs in the final round, Ryan said the Sharks were not to be taken lightly.
"We haven't played a South African team for 16 weeks...we've got to be up for it mentally and physically."
While the Crusaders were likely to see Read and Crotty suit up on Saturday, prop Joe Moody has been ruled out of contention for the squad due to an ongoing knee injury.
