As receiver Koren Robinson hits the open market after a stint with the Packers, which followed a one-year suspension, he’ll now have something else to explain to any teams that might be interested in him.

Robinson’s brother, Tariq, has been arrested for trafficking in ecstasy.  (Not the emotion, the drug.)  The potential problem as it relates to Koren is that Tariq lives with Koren.

The good news is that investigators say there’s no evidence that Koren was involved.  Still, that extra question mark could be enough to scare some teams away.

We’ve previously reported that the Chiefs and Raiders have shown mild interest in Robinson, a top-ten draft pick in 2001.
