Watch WWE 'Night of Champions' [LIVE STREAM] Online: Seth Rollins vs. Sting, John Cena

WWE will air the 2015 edition of Night of Champions from the Toyota Center in Houston, and Seth Rollins will pull double duty tonight when he defends both the WWE World Heavyweight Championship and the WWE United States Championship against Sting and John Cena, respectively. The pay-per-view will air on the WWE Network at 8 p.m. eastern, but if you can't watch there, then try here or here – both of which broadcast free live streams of the show (this may require downloading a torrent).

It's unclear which of these matches will be the main event, as there are some rumors floating around that the United States Championship match could actually go on last. This wouldn't make a whole lot of sense, as the world title should always close the show, especially on a night in which the title belts are the focus of the event.

Plus, Sting is a legend in the industry, so it's not like Rollins is defending the title against a scrub who doesn't deserve to be in the main event.

Regardless of the order of the matches, let's take a quick look at the possible outcomes:

1) Rollins holds onto both titles.
2) Rollins holds onto the U.S. belt but loses the world belt.
3) Rollins holds onto the world belt but loses the U.S. belt.
4) Rollins leaves empty-handed.
5) Rollins holds onto the world belt, but Sheamus cashes in his Money in the Bank briefcase and wins the world title.

But there are even more possibilities within and even outside of the aforementioned scenarios. Sting could win the title and then the Celtic Warrior could cash in on The Icon. Rollins could hold onto one or both of the titles by DQ. Triple H might turn on Rollins and cost him the world title. Sheamus could cash in for the U.S. title.

I have a headache...

We'll predict that Rollins loses all the belts and then Sheamus cashes in on Sting.
