Wrestling News World reader Asim attended Thursday's WWE live event in Leeds, England and noted that World Heavyweight Champion John Cena might have legitimately tweaked his ankle in his match against Alberto Del Rio. The reader that sent the live report posted here didn't mention it.
The same reader, Asim, reported that CM Punk might have been knocked loopy in his match with Daniel Bryan against Luke Harper & Erick Rowan. However, according to the report, Punk walked to the back on his own after being checked out by the referee at ringside. He finished the match with his GTS finisher to get the win.
I am unable to confirm the severity of either injury as of press time as the time difference makes communication difficult. We'll see whether or not either are held on Friday as both are scheduled to work in London.
