"Stone Cold" Steve Austin crashed his way into WrestleMania 41 on Sunday -- quite literally -- 'cause the WWE legend went ramming into a barricade on an ATV during his surprise appearance in Vegas.
Austin had the sold-out Allegiant Stadium crowd going nuts when they heard the glass shatter over the speakers ... and just like he's done in the past, he had a joyride on a four-wheeler as he made his way to the ring.
Except this time, Austin misjudged his turn around one of the corners of the ring .
