Sounds like more bullshit storyline injuries. If he actually broke his pelvis he's be writhing in pain uncontrollably, not laying there motionless.
They really ought to stop doing these fake injury stories because the day someone is hurt for real we'll never be 100% sure if its true or not. Like because of the fake injury angles, some people didnt even believe Lawler had a heart attack for real. They thought it was an angle to get CM Punk over more as a heel.
