Lawyers met Monday at the courthouse, with prosecutors saying they needed more time to work out the agreement.
Pitkin County Chief Deputy District Attorney Arnold Mordkin didn't elaborate.
Yale Galanter, a lawyer for Sheen's wife Brooke Mueller Sheen, says Sheen had reached a deal to plead guilty to a misdemeanor assault charge.
Galanter says the deal would include a 30-day jail sentence, and that Sheen would be able to leave during the day to work at a theater company.
Mordkin wouldn't confirm details but didn't dispute media reports about the work release arrangement.

Charlie Sheen has agreed to plead guilty to a misdemeanour assault charge in his domestic violence case and work at a Colorado theatre company during a 30-day jail sentence, his wife's attorney said.
In exchange, prosecutors would drop criminal mischief and felony menacing charges stemming from an argument Sheen had with his wife Brooke on Christmas Day at an Aspen home where they were on vacation, attorney Yale Galanter said.
The deal called for Sheen to serve a 30-day sentence and serve three months probation, Galanter said.
A judge must still approve the agreement. Sheen was expected to appear on Monday in an Aspen court.
Prosecutors confirmed last week that Sheen reached a plea agreement but released no details.
Neither Pitkin County prosecutors nor Sheen's attorney Richard Cummins immediately returned phone calls seeking comment.
Sheen, the star of the hit CBS show "Two and a Half Men," has pleaded not guilty to menacing, criminal mischief and assault charges. The menacing charge carries a prison sentence of up to three years.
During the jail term, Galanter said Sheen will be released during the day so he can work at Theatre Aspen. He could leave the jail for work at 8am and would have to return by 8pm.
"He's being sentenced to jail, and he's being released for work, thereby, it's work," Galanter said.
Paige Price, the theatre's artistic director, said Sheen has agreed to work for free. Part of his duties would include teaching a class for professional actors and possible fundraising for the nonprofit.
"We think it is community service in that it is a nonprofit," Price said.
Brooke Mueller Sheen approved the deal, Galanter said. She previously asked prosecutors to drop the charges against Sheen but they refused, according to the lawyer.
He said prosecutors had offered a deferred sentence, whereby Sheen would plead guilty to a felony and charges would be dropped after two years, which is similar to the way other cases are resolved in Colorado.
Sheen has taken anger management classes and will present evidence showing he has completed a 36-hour course, Galanter said. "They're both adults, and they have two beautiful babies together. I know they're working on it. I can tell you that no matter what happens, Charlie and Brooke will always be good friends," he said.
Sheen agreed last month to return to "Two and a Half Men" for two more seasons.
