The WWE don't like blood in the PG era - that much is certain. But they're certainly not afraid of using a legitimate injury to add spice to a top feud, and this trend continued on Thursday night. Rollins showed several slow-motion replays of his wayward knee on the TitanTron, claiming that he turned Cena into a Picasso painting and left his nose splattered across the side of his face. It was an example of marvellous heel work by Seth, as well as evidence of the WWE's readiness to adapt.
