Frank Travieso, who raced for the Miami Nights last season, has been given a six-month ban after testing positive for ephedrine during the Gateway Cup last September, USADA announced this week.
"After investigating, USADA determined that Travieso was using a medication containing ephedrine, which he obtained over the counter at the direction of a physician, but he lacked a valid Therapeutic Use Exemption (TUE)," the statement read.
