Chris Tierney jumped over the boards at 17:02 of the first period to help kill a minor penalty. He was on the ice for all of 16 seconds before being swapped out for Couture, albeit briefly.
Tierney came back on the ice at 17:18 and was on the ice until 18:02, at which point he broke free of the San Jose defensive zone and instead of getting a true breakaway opportunity on Ryan Miller was dragged back by the last man standing for Vancouver.
For his trouble, he was awarded a penalty shot. So after expending almost all the gas left in his tank, he had to try to go one-on-one with one of the better netminders in the NHL.
