Cesaro had his ribs taped up for his match against The Miz at last night’s WWE live event in Hampton, VA. They were also taped up for SmackDown when he faced Sheamus.
It looks like he suffered some sort of a rib injury on Raw when Kevin Owens knocked him from the apron to the announce table. He could be playing this injury up a bit, but considering that he had them taped up at the live event, it may be an actual injury and not part of a storyline.
