The Rock returned to WWE television when he interrupted Rusev midway through Monday Night Raw.
The former world champion, who hasn't wrestled for the company since he was beaten by John Cena in the main event of WrestleMania 29, made his comeback during the Bulgarian's promo to a stunned crowd of around 15,000 in Brooklyn, New York.
The pair eventually came to blows, with the 'Brahma Bull' typically getting one over on the unbeaten grappler before sending his opponent over the top rope.
The Rock's unexpected appearance was a one-off, and he is not expected to enter into a series with Rusev.
Elsewhere on the show, Triple H announced that Cena will square off against Dean Ambrose at the Hell In A Cell pay-per-view later this month in a match that sees the victor meet Seth Rollins later that night.
