Commission: Ken Shamrock vs. Kimbo Slice won't happen unless both fighters pass drug tests

A lot of fight fans said that Ken Shamrock's exploding biceps (see them here) were the result of training and nutrition, as well as a fisheye lens, and not performance-enhancing drugs, something that got "The World's Most Dangerous Man" into hot water back in 2009.

We're about to find out.

Shammy will be forced to pass a drug test administered by the Missouri Office of Athletics before he can make his return to mixed martial arts (MMA). In addition, the UFC hall of famer must also be cleared medically, which is not as easy as it sounds at 51 years old.

Mark Raimondi has the details:

Missouri Office of Athletics director Tim Lueckenhoff told MMAFighting.com that both contestants will need to undergo "additional testing" and will, of course, need medical clearance before they are granted a license to compete in the state. Lueckenhoff, who is also the Association of Boxing Commissions (ABC) president, would not go into details about the tests, but Bellator confirmed that it would be similar to how Nevada and California have been testing out of competition. It is unknown if there will be blood and urine tests done or just urine.

There is still plenty of time to get into fighting shape.

Shamrock (28-15-2) is expected to collide with former EliteXC nemesis Kimbo Slice (4-2) -- who will also be tested -- in the main event of Bellator 138 on Spike TV, which is scheduled for June 19, 2015 inside the Scottrade Center in St. Louis, Missouri.
