She is the third celebrity to associate with the League after superstar Akshay Kumar and rapper Yo Yo Honey Singh.
This is the first time Sonakshi has associated herself with a sport of this kind.
"I am really excited to be part of World Kabaddi League. This is my first such endeavour. Kabaddi is a fast-paced sport and I'm looking forward to some adrenaline rush moments during the League,` Sonakshi said in a statement.
She is likely to travel along with her team as much as possible for WKL, which will start in London Aug 9.
Sonakshi is already making changes in her shooting dates so that her commitment to the sporting event is intact.
Talwinder Singh of Hayre Group said: "It gives me immense pleasure to have an A-list actor like Sonakshi to be a co-team owner. Her movies are eagerly watched internationally and am sure she can make Kabaddi look cool as a sport to play and follow."
The organisers of the event are "very excited with the support World Kabaddi League is getting from various celebrated personalities".
"Sonakshi is truly a gem in the crown. We are confident that her association will add to the growing fan following of the League,` Pargat Singh, commissioner, WKL said.
WKL will be played in Circle style which is the most popular kabaddi format followed across 26 countries globally.
