Shilpa Shetty's husband Raj Kundra has collaborated with actor Sanjay Dutt to start a sports venture called Mixed Martial Arts (MMA) league. Kundra says that his wife will stay away from it, but she will be his support system.

Shilpa along with her husband was the co-owner of Indian Premier League's franchise Rajasthan Royals and she was also the face of the team. But right now the 36-year-old has taken the back seat and is enjoying her pregnancy.

"My wife has been my bouncing (sounding) board for the last six months. She keeps telling me the kid is kicking away inside so please no more MMA. You go do what you got to do and I support you in anything you do, " said the businessman, who married Shilpa in 2009, at the announcement of the venture along with Sanjay Dutt.

Meanwhile, Sanjay is eager about his entry into the world of sports and assures that MMA is exciting and not a brash sport.

"I want you all to know it's not like cop fighting in the cage. There are rules and regulations in MMA. If you can watch boxing, then Mixed Martial Arts is more interesting, " said the 52-year-old actor who will soon be seen as villain Kancha Cheena in the "Agneepath" remake.

The first MMA event called Super Fight League will take place in Mumbai March 11 and then it will travel to Chandigarh and New Delhi.

The Mixed Martial Arts industry is a fast-growing sport and is said to be valued at $2 billion in the US alone.
