Yeah, looks like he'll play this week, and any suspension would kick in following the bye in week 6.
Supposed to be 2-to-4 weeks, and I've read that he's got a good chance of getting the smaller hit because A) the 'incident' happened before he signed an NFL contract (though after he was drafted) and B) he's already served a suspension in 2001 as a two-time offender of the drug policy, and negative tests since then suggest he's 'cleaned up his act.'
There's certainly fodder there for his lawyers to appeal the suspension altogether, but I don't see the NFL backing off on this.
Because of this, I've seen a couple reports that suggest Lewis will consider bagging the appeal, jump right into the suspension to get it out of the way, then be ready to roll unburdened for the final 7-9 weeks of the season.
I want to die peacefully in my sleep, like my grandfather.
Not screaming, like the passengers in his car.
