10 Matches That Nearly Made Wrestlers Quit For Good
4. Brock Lesnar Vs. John Cena (Extreme Rules 2012)
'The Beast Incarnate' was not a happy customer after losing his return match to John Cena at Extreme Rules 2012, and not just because of the outcome.
The bout itself was tremendous. Carried by its stiffness, it presented Lesnar in his best light, with his brutal, relentless onslaught leaving Cena a bloodied mess. Superman prevailed, though. He was devastated, but just as he'd done a thousand times before, 'Big Match John' fought through the barrage, eventually putting the former UFC Champion away.
Cena should have stayed down afterwards, selling the damage Brock had inflicted in defeat. He didn't. Instead, John got up to address the crowd afterwards, totally negating everything 'The Beast' had done during the bout, making the returnee look like an ineffective dork in the process.
According to reports, Lesnar threw an almighty s***-fit afterwards. He was furious with the direction, and it supposedly took a pep-talk from Triple H to calm him down, with the tirade leading to immediate speculation that he was already finished with the company. Fortunately, the two parties soon mended fences, but imagine how vastly different WWE would look today had Lesnar's comeback been one-and-done.
