Last night's angle with Triple H to end RAW was the beginning of a concussion angle. At this time, the plan is to keep Triple H off TV for a while, and when he returns the McMahon family (Stephanie and Vince) will try and convince Triple H that he should not wrestle again.
WWE.com has some post RAW video up on the site, showing Triple H undergoing a memory test, selling the idea that he had a concussion from Extreme Rules. During the test, he was asked whether he could remember McGillicutty's new name, which he could not. He also "only remembered" making his entrance, but not the actual match.
