I've heard everything from failed drug test to doing some sort of start-up clothing company endorsement. The latter being the more ridiculous of the two. Probably failed drug test.
Based on what miles said - something on the lines of he violated a rule that would also be a violation with the school - and the fact that BRPD showed up at the presser would lead me to believe that it has to be a drug test. On the other hand is it a two strikes and you're out rule? Seems like kicking off the team is a little severe for failing a second drug test considering how much we put up with Ryan Perrilloux.
ESPN said that 3 failed drug tests are you are out. IF that be true, then Mathieu had another failed test somewhere.
