If he does get suspended at all I imagine it wouldn't be more then 4 games.
But where this guy never been in trouble before, and where he assisted in the case it wouldn't suprise me if nothing happens.
Today's Boston Globe published the NFL substance abuse policy.
First-time offenders enter stage one of a rehabilitation program, where the focus is on evaluation over a period that could be as short as 90 days or as long as six months. There are no suspensions for entering stage one of the program, only the possibility of fines.
Players in stage one can be given a treatment plan, and if they don't follow it, they would be advanced to stage two for up to 24 months (or two seasons).
Players in stage two who fail a test, or are deemed to not be following their treatment plan, are initially subject to fines. A second failed test, or a second incident that shows a lack of following the treatment plan, results in a four-game suspension and elimination from the Pro Bowl if selected.
At that point, a player would advance to stage three and remain there his entire career. Any player in stage three who fails to comply with the program is banished from the NFL for a minimum of one year.
Players in the program are drug-tested regularly, possibly up to 10 times per month.
The NFL keeps the names of players in the substance abuse program confidential, so it is not known in what stage, if any, the 28-year-old Kaczur might be.
So a fine or nothing is a distinct possibility. You need to screw up at least twice to get a 4 game suspension.
