Tonight, live on SHOWTIME, NFL legend and former Heisman trophy winner Herschel Walker will make his long anticipated mixed martial arts debut. The 47-year old will step into the cage against Greg Nagy as part of the Strikeforce: Miami main card.

Let's take a look at where Walker's debut will rank among the top 10 most high profile debuts in MMA history.

10. Latasha Marzolla

Marzolla isn't exactly an A-List celebrity but she is a former Playboy model and even had a brief stint with the WWE. Believe it or not, this voluptuous blonde has been enthralled with martial arts for most of her life. She took up wrestling in high school and eventually transitioned into Muay Thai under the world famous Master Toddy.

The beautiful kickboxer's entrance into the world of MMA opened several eyes considering she has appeared in multiple Playboy Special Editions series and was chosen as the 2004 Model of the Year. In May 2009 the blonde bombshell made her amateur debut stopping her opponent in the first round with strikes.

As an amateur, Marzolla is 2-0 and establishing the reputation for being one of the top prospects in Women's MMA.

9. Mariusz Pudzianowski

At 6'1, 320-lbs Pudzianowski is recognized as the strongest man on the face of the earth. The monstrous pole has won more Worlds' Strongest Man championships than anyone else who has ever competed in the event.

With his immense power and massive frame, MMA fans pondered how Pudzianowski would fair inside the cage.

Well in 2009, "The Dominator" answered those questions with a huge exclamation point. In his homeland of Poland, Pudzianowski pounded on opponent Marcin Najman with punches until Najman submitted from the strikes.

Before the fight Pudzianowski said: "Ta r?ka niesie za sob? smierc, a tej drugiej sam si? boj??" Which in English translates to "This hand brings death, but the other one even I am afraid of."

8. Satoshi Ishii

North American fans might not be familiar with Ishii but in Japan he is a very big deal. Noted for winning a gold medal in Olympic Judo at the 2008 Summer Olympic Games in Beijing, China, a silver medal at the 2006 Asian Games and two All-Japan Judo Championships, Ishii is highly regarded for being one of the best Japanese athletes in the world.

After winning the gold medal, Ishii expressed his desire to transition into MMA. Despite rumors of a UFC signing, Ishii made his debut as part of the Dynamite!! 2009 card in Japan. He would end up losing a unanimous decision to fellow Judoka gold medalist and MMA veteran Hidehiko Yoshida.

7. Jason David Frank

When Frank-who is best known for his role as the Green Ranger in Mighty Morphin Power Rangers-announced he would be making his professional MMA debut he was met with mixed reactions. Some critics believed that the movie star was looking to use MMA's popularity to get his name back out there after his acting career went down the toilet.

What those critics fail to realize is that before being a Power Ranger, Frank was a dedicated martial artist. He is a sixth degree black belt in Shotokan karate and has been involved in martial arts for most of his life. Nonetheless, whether fans support him or not, everyone is interested to see what the Green Ranger can accomplish in MMA.

Frank will make his much anticipated MMA debut against Jonathon "the Mack Truck" Mack January 30th at...
