On the same day Cleveland Browns coach Mike Pettine said Johnny Manziel will start the rest of the season, the 22-year old quarterback found out he will not face discipline for an October driving incident involving his girlfriend.

"Consistent with the procedures of the league's Personal Conduct Policy, we have examined the available evidence regarding the recent incident involving Johnny Manziel," NFL said in a statement said.

"Our investigation included a thorough review of information from law enforcement and our own interviews with multiple individuals, including the two involved in the incident. Based on the information gathered, we have concluded that there is an insufficient basis on which to take disciplinary action. In all cases of this nature, our concern under the Personal Conduct Policy goes well beyond the issue of discipline, and we have made comprehensive professional resources available on a confidential basis."

Calls to 911 on Oct. 12 described Manziel driving at a dangerously high speed on Interstate 90 outside Avon, Ohio. Witnesses told authorities that Manziel cut across several lanes to exit the highway and his girlfriend, Colleen Crowley, had attempted to jump out of the moving car as it exited the highway. Crowley declined to press charges after originally claiming Manziel put her head up against the glass window of the car.

Manziel admitted to having drank alcohol earlier in the day but was not administered a field sobriety test because he did not show signs of being inebriated, according to police. After speaking with authorities, neither Manziel nor Crowley was charged and they were allowed to leave the scene together. Manziel spent 10 weeks in a treatment facility for substance abuse in the offseason.

With seven regular season games left, Manziel takes over for Josh McCown after the second-year pro started the last two games with McCown nursing a rib injury. Manziel had his best game of the season in Week 10, albeit a loss, completing 33-of-45 passes for 372 yards to go with one touchdown and one interception.
