The NFL has notified teams that Michigan's Jabrill Peppers tested positive for a dilute sample at the scouting combine.
Peppers is the second NFL draft prospect to test positive for a dilute sample at the combine, joining Alabama linebacker Reuben Foster.
A spokesman for Creative Artists Agency, the agency that represents Peppers, told ESPN's Adam Schefter that Peppers, who has a history of cramping, was ill after flying to Indianapolis from San Diego, so he drank eight to 10 bottles of water as he was the first athlete to run for both the linebackers and defensive backs.
