Champion boxer Floyd Mayweather denies using banned IV drugs to give himself an advantage over boxer Manny Pacquaio in their May 2 bout.
One day before the boxing match, Mayweather was given an IV containing saline (salt water) and vitamins.
The drugs contained in the IV were not illegal, but the method of administration -- infused directly into his bloodstream -- was forbidden, according to a report on ESPN.com.
