Updating a previous report, Lack has been confirmed as the backup for Ryan Miller in Saturday's game against the Flames, Jim Jamieson of the Vancouver Province reports.It was generally expected that Lack would be in the crease due to his excellent career numbers against the Flames (3-1-0, 1.49 GAA, .940 save percentage), along with the fact that Miller started a day earlier, but coach Willie Desjardins decided to stick with his No. 1 netminder. The Canucks will have another back-to-back set scheduled for the following weekend, which will probably represent Lack's next opportunity to pick up a start.
