Sheamus Injury Update
World Heavyweight Champion Sheamus is being evaluated by WWE medical personnel, following Alberto Del Rio’s vicious assault during SuperSmackDown LIVE: The Great American Bash.
Del Rio – who is known for his flashy ring entrance behind the wheel of a luxury automobile – instead used his car hood to batter The Great White during an intense brawl between the SmackDown rivals.
Sheamus was treated for head contusions and lacerations to the head, rendering him unable to compete in The Great American Bash 20-Man Battle Royal. It remains to be seen what effect this will have on his World Heavyweight Title defense against Del Rio in less than two weeks at the Money in the Bank pay-per-view.
