I'm pretty sure Triple H defended the WWE Championship against Big Show on a Smackdown! back in 2008.WWE.com said:PUNK TO DEFEND THE WWE TITLE ON SMACKDOWN
For the first time in eight years, the WWE Championship will be contested on SmackDown when CM Punk puts his title on the line against Kane. Watch this historic match Friday night at 8 p.m./7 CT on SmackDown!
Anyway, I take it Bryan will get involved, finally setting up a triple threat for No Way Out.
