A new NFL substance-abuse policy would include automatically suspending players who get a DUI, according to NBC Sports' Pro Football Talk.

The proposal includes first-time offenders. It also imposes a fine that amounts to one game check. The new policy will be implemented when an HGH testing agreement is reached.

The current rules require a two-game fine for players who are deemed legally responsible for a first-offense DUI. Usually, suspensions only apply to a second offense.

The league and the NFLPA have haggled for years over tougher penalties. The union may be willing to go along with the policy change to DUIs stemming from former Dallas Cowboys defensive tackle Josh Brent's drunk-driving accident that killed then-teammate Jerry Brown Jr. in December 2012.

The fate of the HGH testing policy depends on whether commissioner Roger Goodell will still have the power to resolve appeals of performance-enhancing drug violations that arise from evidence of drug use aside from a positive test. All appeals based on positive tests will go to a third party for arbitration.
