5 Rare WWE matches that happened only once

#2 Brock Lesnar vs. CM Punk

Paul Heyman played a big role in this match

One of Brock Lesnar's sternest tests on his return to the WWE came in the form of one Mr CM Punk. With Paul Heyman leaving Punk's side to return to his role as The Advocate of The Beast, this was a matchup for the ages.

Both men were in the prime of their careers and put on a hell of a show. Lesnar even required the help of Heyman's interference in order to pick up the victory. A rematch seemed to be destined between the two but it never happened.

These days, of course, Punk has followed the Lesnar route and gone into the world of MMA.
