The 37-year-old, who controversially never played for England, is currently an academy coach for the Canaries.
Holt retired in August to focus his attentions on the world of sports entertainment.
He signed a contract with World Association of Wrestling to fight at their 2019 Fightmare 3 event. However, to the surprise of the crowd, he was the last man out to win a 40-man Royal Rumble on Saturday.
After almost being thrown out of the ring, Holt clambered back in with the help of another wrestler to win the bout with a drop-kick.
The striker made 154 appearances for Norwich, scoring 68 goals. Despite scoring 15 goals in his first season in the Premier League, he was denied an England call-up for Euro 2012.
