Dallas' CBS affiliate, KTVT, first reported Wednesday that Jones was involved in an altercation at the Joule Hotel in Dallas, damaging a bathroom.
Dallas Deputy Chief Vince Golbeck told the Dallas Morning News police were called to the scene at 1:30 a.m. Wednesday. Chief Golbeck told the News he thought Jones was staying at the hotel and may have been drinking.
There was no police report filed regarding the incident. No one was arrested and no one will be charged in connection with the fight.
"Someone from the business called police," Dallas police spokesman Cpl. Jerry Monreal told The Associated Press. "Police arrived and spoke to the parties after they had a verbal argument. Both parties agreed to leave, and they left."
Worrick Robinson, Jones' attorney, told ESPN's Ed Werder that he had a conversation with Jones on Wednesday about the alleged incident.
"I'm not satisfied anything has happened,'' Robinson said. "I perform due diligence on rumors anytime there is an allegation made against a player I represent, and at this point I can tell you that I'm not satisfied that anything occurred.''
NFL spokesman Greg Aiello had no comment. The Dallas Cowboys said they had no information about the incident and also had no comment.
A source told ESPN that NFL Security has been notified and is investigating.
It was apparently a coincidence that NFL commissioner Roger Goodell visited Cowboys players at their Valley Ranch training complex Wednesday. Goodell suspended Jones from the league for the entire 2007 season for violating the NFL player conduct policy.
Before meeting with the Cowboys on Wednesday, Goodell said to reporters in San Antonio: "Adam knows how much emphasis I put on making sure that he makes good choices going forward, that he avoids situations where he can reflect poorly on himself, the Cowboys or the NFL. So far he seems to have been able to do that very effectively.
"I am supportive of him and am hopeful that he will be able to do that for the rest of his life. I am hoping he will not only be a great NFL player but he will continue to do the right things so he can lead a productive life off the field as well."
Goodell suspended Jones in April 2007 after an accumulation of arrests and legal problems.
At the time of his reinstatement Aug. 28, Jones said: "I know my responsibilities to the NFL and I'm going to hold my own and do what I need to do to make sure I stay where I am right now, which is reinstated. I work hard every day to make sure I don't make the same mistakes. Can I say I would never ever make the same mistakes? No, I can't say that. I'll make sure I put myself in way better situations than I have put myself in the past."
The Cowboys acquired him from the Tennessee Titans in a historic trade in April. Jones became the first player in NFL history to be traded while serving a suspension.
The expectation is that Jones is likely to be called to New York to explain his conduct to Goodell, a source close to the player said. Jones' reinstatement is contingent upon his ability to conduct himself appropriately.
Deion Sanders, who has acted as a mentor for Adam Jones since his arrival in Dallas, was also at Valley Ranch on Wednesday, ESPN.com's Matt Mosley reported.
Compounding the potential consequences for the Cowboys is that Jones has been starting at left cornerback for Pro Bowler Terence Newman, who is attempting to confirm a preliminary diagnosis of a sports hernia injury that could sideline him for a minimum of six weeks if surgery is required.
In a sitdown interview with ESPN just before the start of the NFL season, Jones explained his decision to provide Jones with a four-man security detail at the team's expense.
"We have in place a staff here that really is good at monitoring what our players do," the Cowboys owner said. "Now I say this at the risk of knowing that in the next minute or in the morning I could get a phone call. ...When you're dealing with the numbers of people that we're dealing with and get some news that isn't too savory. On the other hand, this does call for an awareness on the part of any player that he is being monitored and the reputation of our team is at stake."
In his two decades of owning the Cowboys, Jones has established a reputation for taking risks on players who fit a specific profile. Jones says they must have a uniquely big work ethic, an intensely competitive personality and no history of substance abuse.
Before completing the trade, Jerry Jones told ESPN he sent investigators to Tennessee to research every incident in which Adam had been accused of wrongdoing and was so thorough in his background check that he and an assistant personally looked into every person to whom Jones wrote a personal check to determine the quality of people with whom he was associating.
Jerry Jones said he specifically informed Adam Jones he had lost most of his benefit of the doubt and underscored the privilege of playing in the NFL and wearing the Cowboys uniform.
"When we do have a player come to the Dallas Cowboys," Jones said, "I really do expect him to understand that, 'Look you've stepped on some bright lines you may even have gone over them certainly, and we've got to really get it back in the middle because all your benefit of the doubt is gone.'"
