5 Superstars who shocked WWE by quitting

#3. CM Punk

Punk as WWE Champion, which he held for 434 days.

Whilst fans still hope to see the Voice of the Voiceless return, it seems more unlikely with every passing day. Punk has made it clear that he has no intentions to return to WWE, instead focusing on his UFC career.

Punk quit the WWE the night after the 2014 Royal Rumble, later claiming that he had been wrestling whilst sick and injured for months, and said WWE were aware of it. After being suspended for walking out, Punk was later given his termination papers on his wedding day (when he married fellow WWE alum, AJ Lee).

Irate, Punk vowed to never return to wrestling, and despite fans' hopes, has kept true to his word. Nowadays you can find him in UFC, where he has a 0-2-0 record.
