Former Florida wide receiver Antonio Callaway tested positive for marijuana at the NFL combine, reports ESPN's Adam Schefter.
According to Schefter, Callaway's new agent Malki Kawa, who didn't represent Callaway during the combine, said it was for a diluted sample.
A diluted sample is treated as a positive test result.
Callaway has had previous off-the-field incidents at Florida.
He was suspended from team activities during the spring semester in 2016 after a woman accused him of sexual assault. Callaway was found not responsible at a hearing last August and placed back on the team.
