Raji failed combine drug test. Apparently tested positive for marijuana in college, and missed 2007 for academics.
Obviously won't fall to 32. Teams that let relatively minor drug issues sway them will remember Warren Sapp and Randy Moss dropping down the boards. But the academic issue, confirmed by the fact that he's not got enough going on upstairs to realize he'd be tested at the combine, may be the bigger problem.
Won't affect the Steelers really, just be interesting to see where he ends up.
