Since the coining of the term “mixed martial arts” in 1993, the sport has become one of the most popular in the world. As public interest has spiked, more and more professional athletes seem to be flocking to the sport. Whether looking to continue competing after retiring from their original sport or simply pursuing a new passion, here’s a look at some of the athletes who have given MMA a shot.

What Is MMA?


Before delving into the various athletes who have tried MMA, it’s worth taking a look at what the sport actually entails. Mixed martial arts is defined as a full-contact combat sport that allows grappling, striking and fighting techniques from various other sports, including wrestling, kickboxing and karate. Though general physical fitness is important, MMA involves its own intensive training, often involving a combination of jiu-jitsu, muay thai, judo and other mixed disciplines.

Athletes Who Tried MMA Have Gotten Mixed Results


The world of mixed martial arts has drawn athletes of all kinds over the years, including former NFL stars, longtime wrestlers and even several past NBA players. Though it may seem like an easy transition to move from one competitive sport to another, it’s not as simple as it looks. While some have been able to successfully make the leap, others who have tried their luck at MMA have gotten not-so-great results — including the first name on our list.

Jose Canseco


You know Jose Canseco from his long career as a baseball player for the Oakland A’s and the New York Yankees. During his years in MLB, Canseco became a six-time All-Star and won a World Series with each team. But his baseball career came to a screeching halt after a steroid scandal landed him in legal trouble and ruined his reputation. 

Following the incident, Canseco attempted a career in MMA, although that also didn’t go as planned In 2009, he faced off against Korean opponent Choi Hong-man at the Dream 9 in Japan and lost by submission just a minute and 17 seconds into the match. That remains his one and only MMA match. 

Brock Lesnar


Brock Lesnar has enjoyed a long career as a professional wrestler, signing with the WWE back in 2000. Throughout his years in wrestling, he’s taken several hiatuses to explore other sports. In 2004, he was named a defensive tackle for the Minnesota Vikings, although he was cut prior to the start of the season. In 2006, he also pursued a career in MMA and eventually signed with the UFC in 2008. He continued to compete in matches on and off in the ensuing years, although his most recent victory in a 2016 bout was overturned after he tested positive for a banned substance. He has since retired from MMA, although he continues to wrestle.  

Matt Mitrione


Another former NFL star to join the world of MMA is Matt Mitrione, who previously played for the New York Giants and the Minnesota Vikings. He made his professional MMA debut in 2010, defeating Marcus Jones via knockout. Since then, he’s built a record of 13 wins, 6 losses and 1 no contest. He signed with Bellator MMA in 2016 and continues to compete for the organization.

Herschel Walker


Herschel Walker is best known as a former football star, having played at the University of Georgia before joining the NFL as a member of the Dallas Cowboys. However, he has participated in a variety of sports besides football, including bobsledding, track and field and, yes, MMA. After first expressing his interest in martial arts in 2007, Walker went on to sign with the heavyweight division of MMA promotion company Strikeforce in 2009. His MMA career didn’t last long though. He has only competed in two professional matches, although he won both of them.

James Toney


James Toney competed as a professional boxer from 1988 to 2017, winning multiple world championships in three different weight classes along the way. After attending a UFC match in 2010, Toney signed a multi-fight deal with the organization, although it didn’t last very long. After losing his debut fight against UFC Hall of Famer Randy Couture in 2010, Toney was released from his contract.

Holly Holm


To say Holly Holm knows how to hold her own in a fight would be the understatement of the century. The athlete has now successfully competed as a professional boxer (winning multiple welterweight titles and a record of 33-2-4), a professional kickboxer (14-1-7) and an MMA champ (12-4). Holm’s most notable win in MMA occurred in 2015 when she defeated Ronda Rousey and captured the bantamweight title, causing one of the big upsets in the sport’s history.

Jake Hager


Jake Hager (also known by WWE fans as Jake Swagger) also recently made the jump to MMA. The athlete was an All-American wrestler in college and turned pro in 2006. During his time with WWE, he won both the World Heavyweight Champion and the ECW Championship. Despite his success, he left WWE in 2017 in order to pursue a professional MMA career. Hager signed a contract with Bellator MMA later that same year and had his first pro fight in January 2019, where he won in the first round against J.W. Kiser.  

CM Punk

After retiring from wrestling in 2014, he signed with the UFC to pursue an MMA career. Unfortunately, his early bouts haven’t exactly been a victory. In his first professional fight in 2016, he was defeated via submission, and he lost his second match in 2018 via unanimous decision. 

Bob Sapp


Bob Sapp began his athletic career as a football player, playing for the Chicago Bears and the Minnesota Vikings.

Greg Hardy is one of several former NFL players to turn to MMA as a second career. The former defensive end played for the Carolina Panthers from 2010 to 2014 and later joined the Dallas Cowboys as a free agent.
