Memphis Grizzlies' Mayo says banned substance was in 'energy drink or something similar'

Grizzlies guard O.J. Mayo said the product that included a banned substance and led to his 10-game suspension without pay by the NBA was purchased at a local gas station.

When asked to name the product or why he used it, Mayo declined to give specifics.

“It was an energy drink or something similar,” Mayo said. “It was bad judgment on my behalf because I maybe should have gotten it checked out by Drew (Graham, the team’s athletic trainer). I can’t go too much into it because of the NBA.

“It’s not like I went to a GNC and got some kind of muscle armor or something,” Mayo said. “Or ordered some supplement off the internet or anything. A local gas station got me hemmed up. I’ve definitely got to make better decisions. I admit to my mistake and it’s something I got to deal with.”
