Holt, 37, currently player-coach at National League side Barrow, has agreed a deal with the British professional wrestling promotion to appear in more than one of their shows.
“Wow @Grantholt31 will be in action at waw supershow,” WAW revealed on Twitter on Thursday.
WAW said Holt will appear in its Fightmare 3 Supershow in 2019, while BBC Radio Norfolk have also reported he has signed a contract to become a professional wrestler.
The former Nottingham Forest forward will team up with Roy and Zak Knight, also known as the UK Hooligans, on WAW’s show.
WAW was founded by Ricky Knight, Saraya Knight and Jimmy Ocean in Norwich in 1994.
Ricky and Saraya Knight’s daughter Paige currently appears on American promotion World Wrestling Entertainment (WWE).
A film about Paige, Fighting With My Family, written and directed by Stephen Merchant and starring Dwayne Johnson, is scheduled for release in March next year.
Grant has scored over 150 goals in more than 400 career appearances as a footballer, with Rochdale, Shrewsbury and Wigan also among his former clubs.
