Source: Marvin Lewis talks hit snag

Talks between the Cincinnati Bengals and coach Marvin Lewis hit a significant snag by midday Tuesday, a team source said.

Lewis' contract expires after the season. The two sides met Monday and twice Tuesday morning.

After one of the meetings, a person involved said he expected a deal to get done in the next 24 hours. However, in subsequent meetings, the two sides could not come to an agreement on how the franchise should be run.

The Bengals announced on Twitter that no agreement has been reached.

On Monday, Lewis told owner Mike Brown what needs to change for him to consider staying in Cincinnati, where he's had two winning records in eight seasons. The Bengals completed their worst season under Lewis, finishing 4-12 with a loss in Baltimore on Sunday.

Neither Lewis nor Brown would discuss their meeting. Brown said through a team spokesman that a resolution could come as soon as Tuesday.

Lewis wants changes in how the organization operates, including more control over roster decisions. He also has lobbied years for a covered practice field -- the Bengals are the only northern NFL team without one. Lewis turned down an extension last season, saying their differences had to be resolved before he would agree to stay.

The Bengals have only two winning records in the 20 years since Brown took over the team. They went 15 years between playoff appearances before Lewis led them to a division title in 2005. He was coach of the year last season for getting the Bengals to the playoffs again.

The playoff appearances were more of an anomaly, and Lewis wants to change how the front office works to get the organization on solid footing. The Bengals have never won back-to-back division titles.

Lewis' overall record in Cincinnati is 60-69-1.
