According to a source within WWE, Triple H suffered a minor injury during the Raw Elimination Chamber match at WWE's Elimination Chamber PPV.
I was told the injury occurred when Sheamus delivered the Celtic Cross/Razor's Edge finishing move to Triple H, and following the match, Triple H's shoulders and back were said to be in extreme pain. As a result of the injury, Triple H did not appear on Raw the following night, and had very limited participation in the show's dark match main event.
As far as Sheamus is concerned, I was told that there is NO heat on the former WWE Champion, as the bump was both delivered by Sheamus and taken by Triple H correctly. The source I spoke with told me that the injury was a sign of Triple H getting older, and not the result of a botched spot.
The injury is not expected to keep Triple H out of action, however I was told that he's still feeling pretty banged up at this point.
