I exclusively reported earlier that Triple H suffered a minor injury at WWE's Elimination Chamber PPV, and as reported before, Sheamus suffered an injury at the PPV during the Raw Elimination Chamber match as well.
As noted here on the site, Sheamus suffered a concussion during the chamber match, and subsequently was pulled from the Raw taping the next night.
I was told, however, that Sheamus wanted to work the taping, and felt that he was capable of working, however, he was not cleared by WWE as they felt the severity of his injury at the PPV should keep him out of the ring on Raw.
I was told that Triple H has explained to WWE talent in the past that if you suffer an injury during a match, you need to do all that you can, if possible, to gut it out and finish the bout. However, if you are incapable of working a date following the injury, or if WWE management feels that you are not capable of working, then you must sit out even if you feel capable of working.
