Foster told Rapoport that it was a diluted urine sample, but that's treated as a positive test by the NFL.
The positive result came from a diluted sample.
Rapoport says that Foster has been telling people intentionally, including teams that may be interested in him.
"I couldn't eat much, but I had to drink water and Gatorade", Foster told Rapaport.
Alabama linebacker Reuben Foster is considered to be a top five prospect in the 2017 NFL Draft class. Since this can be done to disguise a positive test, the National Football League views a diluted sample as the same thing. I don't care what everybody thinks, but I care what coaches think. He said he was sick before the combine, and he saw a doctor, received medication and started hydrating himself.
Foster attributes it to food poisoning. A potential Foster-Mosley pairing in the middle of a Dean Pees defense is a ticket I can very much get behind. "I hope I go on Thursday, but I can't control that". "Then I went in there, drinking and drinking water, trying to flush out my system from whatever was making me sick and trying to keep my weight up and took the test".
The Ravens picking him in the first round was an idea that I put forward in my most recent first round mock, and I was thoroughly put in my place by several commenters who either hated the pick, or scoffed at the idea that I had them trading up to get him. He also had an altercation with a hospital worker and was sent home before he could finish his medical exam, per Rapoport.
It's been a rough pre-draft process for the former All-American linebacker.
Foster was being tested there following rotator cuff surgery in his right shoulder that would have prevented him from working out at the combine, and he was not healthy enough to perform at his pro day the following week.
