Here's what PWInsider said about the suspension, they are THE most reliable site on the net for this sort of thing:
The WWE website posted a statement attributed to Randy Orton tonight, noting that he was suspended for not following the type of conduct that WWE wants from its performers. The statement did not delve further into the situation.
As noted yesterday on the PWInsider.com Elite section, the suspension came about due to WWE's unhappiness with Orton's attitude and demeanor and it was a situation that had grown over time as opposed to a singular incident. Rumors that the suspension were related to any recent drug testing from the WWE Wellness program were shot down by sources within the company.
Orton is expected to make several more appearances on Smackdown and will then begin serving his 60 days suspension.
As for the question earlier about when a guy starts fighting for real: This is called "shooting" or "going into business for yourself". Shoots are very much discouraged, and extremely rare. When a shoot does occur, the recipient knows immediately, and referees are usually then able to get word to the back via hand signals, or if this were to happen in WWE, they'd have an ear piece giving them a direct connection to the back. It then falls into the hands of the management to decide how to handle the situation. When Perry Saturn did it in WWE (and Bob Holly as well), WWE allowed the shoot to continue until the match stopped, and then reprimanded the individual (in Saturn's case, it led to his being fired from the company), in the case of the indy example that was mentioned, the decision was made to send someone out to the ring and stop the match immediately.
