As previously reported, John Cena underwent surgery last Wednesday to repair his torn pec. They didn’t know the severity of the injury until they went inside and once inside they discovered the tendon had torn all the way off of the bone. The reason they operated immediately as opposed to try and have Cena work No Mercy was partly because six days would have caused the tendon to start shriveling up and operating immediately made the surgery go easier and gave Cena a better chance of coming out of it 100%. As previously noted, Cena is expected to miss WrestleMania next year.
There is some talk within WWE to bring back Tough Enough, in some form. Triple H and Stephanie McMahon are against the idea as they feel that it exposes the business. Kevin Dunn, among other top people in the company are strongly in favor of the idea. Vince McMahon is actually the one who brought the idea back up as he feels WWE needs to put some reality TV into all three of the brands.
