According to WWE sources, Alberto Del Rio’s black eye seen at SummerSlam was not from Christian’s killswitch on SmackDown as the announcers claimed on the pay-per-view.
Although details are sketchy at the moment, Del Rio and Drew McIntyre were involved in a massive real-life fight over the weekend. The fight took place either Saturday night or on Sunday before the pay-per-view.
There may have been other people involved but both Del Rio and McIntyre were beaten up when they returned to their hotel.
