The NFL substance-abuse policy states: "Discipline for a second or subsequent offense is likely to be a suspension, the duration of which may escalate for repeat offenses."
The league has been waiting to make a ruling until after Robinson's case had been concluded. At this point it seems like a formality that the DT will miss time. The only question is, how much? The penalty will likely range between two to four games.
If Robinson does miss any extended period of time, the Bears have depth on the interior of the defensive line. Robinson moves to DT permanently this season and split time with veterans Ted Washington and Keith Traylor.
