Agent: Teams aware of Dwyer's history

Georgia Tech running back Jonathan Dwyer tested positive at the NFL scouting combine for amphetamines, FoxSports.com reported Sunday, but 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.

"I have had it since I was in the fifth grade," Dwyer said. "Georgia Tech knew about it when I went there. The NCAA knew about it before every drug test I took there. And the league knew about it before the combine as they got several letters from my doctor who prescribed me the medication."

Dwyer, who leaves Georgia Tech as a junior, rushed for 1,395 yards and 14 touchdowns as the Yellow Jackets reached the Orange Bowl and finished 11-3.

FoxSports.com also reported USC tight end Anthony McCoy tested positive at the combine for marijuana.
