Peterson was indicted in September on charges of reckless or negligent injury to a child after authorities said he hit his 4-year-old son with a switch. He was deactivated by the Vikings and later agreed to be placed on the Commissioner's Exempt list until his court case is resolved.
The 29-year-old faces up to two years in prison and a $10,000 fine if convicted on the charges. A tentative trial date had been set for Dec. 1, but a plea deal could end the process sooner.
Last month, it was reported that Peterson could still face a suspension for violating the NFL's personal conduct policy even if found not guilty for the charges.
Only commissioner Roger Goodell can reinstate Peterson off the exempt list. Peterson continues to receive his $11.75 million salary this season while he is inactive.
On Oct. 22, a request to remove the judge handling Peterson's case was denied. Prosecutors in the case had accused the judge of being biased against them, and wanted someone else to handle the trial.
