Manziel came to an agreement with prosecutors in a Dallas courtroom. The judge indicated Manziel and former girlfriend Colleen Crowley had an "agreement in principle" to drop the charges.
Terms of the agreement were not disclosed.
Manziel's attorneys and prosecutors have two weeks to file court documents and finalize the agreement. The sides will reconvene Dec. 1.
Manziel was indicted in April by a Dallas grand jury in connection with an alleged Jan. 29 incident with Crowley at a Dallas hotel.
Crowley said she got into a confrontation with Manziel that continued to the valet stand. She was forced into a car while pleading for help and when Crowley tried to jump out of the car, Manziel allegedly hit her.
Manziel posted bond May 4 after being charged with misdemeanor assault. He was not banned from traveling or consuming alcohol.
Manziel was also prohibited from being within 500 feet of Crowley for two years and possessing firearms. He also was instructed to pay Crowley's estimated $12,000 in legal fees over the next two years.
Before the January incident, Manziel was pulled over for fighting with Crowley in Oct. 2015. He was not charged but admitted to having alcoholic drinks before the incident.
Since his indictment, Manziel was released by the Browns on March 16. A first-round pick of the Browns in 2014, Manziel appeared in 15 games and completed 147 of 258 passes for seven touchdowns.
In his brief time with the Browns, Manziel had his work ethic described as "a 100 percent joke" by an anonymous teammate and also spent two months in rehab following his rookie season. Last November, he was demoted to third-string quarterback after video surfaced of him partying on the on the internet.
Before being named the Aggies' starting quarterback, Manziel was arrested and charged with disorderly conduct, failure to identify and possession of a fictitious driver's license from a late-night in College Station, Texas on June 29, 2012. In July 2013, he pled guilty to failure to identify and had the other two charges dismissed.
Following his freshman season, he was kicked out of the Manning Passing Academy for allegedly oversleeping and was ejected from of a fraternity party at the University of Texas.
In Aug. 2013, the NCAA investigated whether Manziel accepted payments from signing autographs. No evidence was found that Manziel took money but he reached an agreement to sit out the first half of Texas A&M's season opener.
