VANCOUVER, B.C. -- Of all the potential changes that were possible for both teams heading into Game 5 of the Western Conference, the Canucks are the only team making a lineup change and it's a small one at that with Victor Oreskovich going in to play right wing on the fourth line for Alex Bolduc.
However, the Sharks showed three new forward lines in warm-ups for the first time in the series. Only their fourth line with Jamie McGinn, Andrew Desjardins and Jamal Mayers remained in tact.
It appears Logan Couture will move up to play Patrick Marleau and Joe Thornton on the top line. Joe Pavelski will center the second line between Ryane Clowe and Devin Setoguchi. Dany Heatley, who hasn't produced in the series, is now on the third line with Kyle Wellwood and Torrey Mitchell.
These were the same lines that the Sharks used in the third period of Game 4, when they ripped 17 shots at Roberto Luongo and scored two goals.
Vancouver defensemen Christian Ehrhoff and Aaron Rome are both still out with injuries, so the Canucks' third pairing will again be Keith Ballard on the left side and Chris Tanev on the right.
San Jose defenseman Jason Demers is also not in the lineup despite saying Tuesday morning that he is 100 percent ready to go after overcoming some bumps and bruises in his upper body that kept him out of the first four games of the series.
Here are the lines and defensive pairings that each team showed in pre-game warmups:
Patrick Marleau - Joe Thornton - Logan Couture
Ryane Clowe - Joe Pavelski - Devin Setoguchi
Torrey Mitchell - Kyle Wellwood - Dany Heatley
Jamie McGinn - Andrew Desjardins - Jamal Mayers
Dan Boyle - Douglas Murray
Ian White - Niclas Wallin
Kent Huskins - Marc-Edouard Vlasic
Daniel Sedin - Henrik Sedin - Alex Burrows
Chris Higgins - Ryan Kesler - Mason Raymond
Raffi Torres - Maxim Lapierre - Jannik Hansen
Tanner Glass - Cody Hodgson - Victor Oreskovich
Dan Hamhuis - Kevin Bieksa
