Georgia Tech running back Jonathan Dwyer tested positive at the NFL scouting combine for amphetamines, according to a report by FOX Sports. Dwyer's agent said teams were aware of his client's medical history. "All 32 teams received notification prior to the combine that a medication he's taken since childhood would likely result in a positive result at the combine," Adisa Bakari told ESPN's Joe Schad. "We provided the necessary medical documentation." Dwyer told Schad the medication is for an attention deficit disorder. The NFL calls Dwyer's situation a "therapeutic use exemption," a source told Schad.
