Rich Cimini of ESPN.com passed along news of the punishment, which also includes probation. Cimini noted the resisting arrest charge will be removed from Richardson's record once the probation is complete. He could still face punishment from the NFL.
Richardson was previously suspended for the first four games of the 2015 season for violating the NFL's substance-abuse policy. Ian Rapoport of NFL Network reported in November that the league was waiting until the resolution of the case to make a ruling about the July incident.
Alan Scher Zagier of the Associated Press reported Richardson's defense attorney doesn't expect further league discipline, however.
Conor Orr of NFL.com provided details of Richardson's arrest in Missouri, which included being clocked at speed in excess of 120 mph with a 12-year-old child in the backseat. Prosecutors opted against filing felony child endangerment charges in the case, though.
Richardson expressed regret over the situation, which came to light shortly after the lineman had apologized to teammates for his prior suspension, as Seth Walder of the New York Daily News noted in early August.
"(It's a) wake-up call," Richardson said. "What I said yesterday, I still mean today. ... I promise you won't hear my name again."
The 25-year-old defender ended up appearing in 11 games for the Jets during the 2015 season. He registered 35 combined tackles, five sacks and two forced fumbles as a key cog in the middle of the fourth-ranked defense.
New York's front office will hope his attorney's prediction of avoiding another suspension is accurate and that Richardson lives up to his word of staying out of the negative spotlight moving forward.
