Stone Cold Steve Austin and Kevin Owens' KO Show segment will reportedly main event WWE WrestleMania 38 night one.

Brock Lesnar v Roman Reigns will main event WrestleMania 38 night two, but fans have been going back-and-forth online about what will main event the first night.

Many fans speculated that WWE would choose Ronda Rousey v Charlotte Flair as the main event over Bianca Belair v Becky Lynch, but that apparently won't be happening.

Reddit user Kerrmit125, who the moderators on the platform have deemed to be reliable, has now revealed what will be main eventing WrestleMania 38, and fans have been left surprised.

The user is reporting that the KO Show segment between Stone Cold Steve Austin and Kevin Owens will main event WrestleMania 38 night one.

That's a pretty big deal for WWE, arguably the second biggest night of wrestling of the year will not be main evented by a match.

However, this shouldn't be too surprising though, considering WWE is promising that Stone Cold will be getting more physical than he has been at any point over the last 19 years.

For what it's worth, the user also reports that the aforementioned match between Becky Lynch and Bianca Belair will be WrestleMania 38's first match.

Adding to that, they report that Cody Rhodes v Seth Rollins, as has since been corroborated by reputable sources, will be taking place on WrestleMania night two.

As of right now, these are the plans. However, as we know when it comes to WWE, the plans are always subject to change over the coming days.

Some have speculated that the segment between Austin and Owens closing night one could lead to a proper match on night two, but that hasn't been confirmed or even reported as of right now.
