Here is what transpired with Leonard Little, DE for the Rams who went through a similar ordeal. This is taken from Wikipedia:
Manslaughter Conviction
After attending a drunken birthday party in 1998, Little crashed into and killed another motorist, Susan Gutweiler in St. Louis, MO. When tested, his blood alcohol level measured 0.19 percent, a level that exceeds the statutory level of intoxication of 0.08 in the state of Missouri. Little received
90 days in jail, four years probation and 1000 hours of community service. The NFL suspended Little for 8 games that year.
Second arrest
Six years later, in 2004, Little was again arrested for drunk driving and speeding.[5] The probable cause statement filed by police said Little had bloodshot and watery eyes, smelled of alcohol and failed three sobriety tests. Because of Little's 1999 guilty plea to involuntary manslaughter in his drunken-driving crash case, prosecutors charged him as a persistent offender. This made it a felony case. Little
was acquitted of driving while intoxicated, but was convicted only of the misdemeanor speeding charge.

Seems like Stallworth should be just fine...
