Defensive tackle B.J. Raji, whose draft stock has soared over the past six months, had a positive drug test at February's combine, NFL team sources have told SI.com. It's unknown to SI.com which drug triggered the positive result, but NFL scouts were made aware before the 2008 season that Raji had tested positive for marijuana during his time at Boston College.

NFL teams will receive the official list of those who tested positive in Indianapolis later this month, and Raji's name will be on it, according to a source who attended last week's owners meetings in California.

Brian Murphy, Chief Operating Officer of Athletes First, which represents Raji, told SI.com: "We will not comment on rumors from unnamed sources. I do know that B.J. has been one of the hardest workers and nicest individuals that we at Athletes First represent. There is no doubt that he will be an invaluable addition to an NFL team both on the field as a player and in the community as a role model."

Raji declined comment when reached by SI.com.

According to the NFL's drug policy, a positive test for street drugs, which includes marijuana, puts a player into the initial stage of the NFL's drug program. He's then subject to random testing and subject to a fine or suspension if he tests positive again.

How this affects Raji's draft grade remains to be seen. He missed the 2007 college season with academic issues, returned to Boston College and had a terrific senior campaign, recording eight sacks and 42 tackles, with 16 tackles for loss. He was a dominant force during the week of practice at the Senior Bowl and continued his momentum up draft boards after turning in good combine and pro-day workouts. His performances the past three months have some scouts believing he'll be taken in the top third of the first round of the April 25 draft.

One source familiar with the positive drug test assessed Raji's draft prospects by saying, "It's a roll of the dice. If Raji stays clean and plays to his potential, you could have a dominant defensive lineman on your team. Then again, it does nobody any good if the kid is on the sidelines serving a suspension for a failed test."

Prior to the 1995 draft, top-rated defensive tackle Warren Sapp saw his stock slip after reports surfaced of positive drug tests during his time at the University of Miami, which he denied. The Tampa Bay Buccaneers eventually selected Sapp with the No. 12 overall pick. Sapp went on to play 13 seasons in the NFL, earning seven trips to the Pro Bowl.

Remember CJ admitted trying marijuana.

CJ admitted trying MJ (i believe once) at some point in his Life (Can't rem if it was HS or College years).

Raji failed a drug test AT THE COMBINE. meaning recent use most likely.

Even if it is only MJ , your back to "What kind of decisions does this player make", the same type of questions people have about Andre Smith.

pot doesn't stay in your system THAT long, so he must have hit the beer can bong a week or so before the combine...if he tested positive for it, don't spend any money on the clown.

No more C-Rog BS

If your not an everyday pothead than yes THC will leave your system in at least 3 days of smoking. But THC is fat-soluble so a bigger guy like Raji has more fat cells so it could be stored for much longer.
I would love to see this drop him to our 20th pick but I don't see it happenin

It depends on the test they do, Im a big guy (near 300) and pot (that i dont smoke ) is gone within 2 weeks MAX, for a urine test.

I know a lot of drugs can be detected by Hair Samples however (not sure if pot is one of them) and Hair samples last for a long long time. Id imagine if it was hair a LOT more players would end up busted at the combine however, so I am going to assume its Urine which means it was at most 2-3 weeks ago... Meaning hes a DUMBASS, even if hes a talented dumbass.

I've had friends social smoke and test a month later and fail (because they listen to people like you guys that say, ohh it's gone in a few days, your good). I'm telling you, you guys simply cannot come to any sort of conclusion that he did it recently, because you do not know. Everyone's body is different. Everyone's metabolism is different. All you know (don't even KNOW its mj) is that he has done it a least one time since winter of '09. That could be a few days to well over a few months, he's a big, big, boy. Anything else is speculation.

The fact that the test is a urine test makes it more speculative. They aren't as accurate at detailing when someone used drugs (like mentioned above, the more expensive hair follicle test can go down to how many days it's been, not weeks or months).

Also like said above, I doubt he makes it past Denver (hey, he'll be happy playing at the old Mile High stadium, right?)
