Just try to remember - it's on TV.
By the way, whoever wins this game - in regulation, in overtime or in a shoot-out - will advance to the Western Conference Finals against the L.A. Galaxy. And the way RSL and Seattle have played each other this season - a 1-0 RSL win and three 0-0 ties - one goal just might do it.
Also tonight, Holly, a Shetland sheepdog from Magna, and her owner, Shanna, will be featured on the 2012 Hero Dog Awards (6 p.m. Hallmark).
