When news surfaced this morning that Broncos linebacker Von Miller is facing a six-game suspension for violating the NFL’s substance-abuse policy we noted that something out of the ordinary must have taken place: Usually a first suspension under the league’s substance-abuse policy is for four games while a second suspension is for a full year. A six-game ban would represent an unusual middle ground.

Now we have some idea of the unusual circumstances that may have led to the NFL planning to give Miller more than the normal four-game ban for a first suspension. Adam Schefter of ESPN reported that when Miller went to give a urine sample to the drug tester it was spilled. When Miller then came back later to give the drug tester another urine sample that sample was found to be diluted.
