Per a league source, the new substance-abuse policy (which will be implemented once an HGH testing agreement is reached) would impose a one-game suspension for a first-offense DUI. The penalty also would include a fine in the amount of one game check.
Currently, the rules require two-game fine for players who ultimately are deemed to be legally responsible for first-offense DUI. Barring unusual circumstances, a suspension arises only for a second offense.
