Former LSU Quarterback Zach Mettenberger’s NFL draft stock took a ding Monday night when Fox Sports broke the news that the NFL determined he had a diluted urine sample at the NFL Combine. 

The NFL considers the diluted sample a failed drug test.  Mettenberger's camp says the simply has been over hydrating to compensate for a knee injury.

Still, some pundits say Mettenberger has the best arm in the draft and he is still ranked as high as the fourth best quarterback available. 

Mettenberger and former LSU defensive tackle Anthony Johnson are two of a reported 10 NFL combine participants who did not pass drug tests. 

As many as 10 LSU Tigers could be selected in the draft Thursday night.  You’ll hear the first round of the NFL draft here on 1130 the Tiger.
