Bengals defensive back Shawn Williams was suspended without pay for one game for a violation of unnecessary roughness and unsportsmanlike conduct rules for stepping on an opponent - Dolphins offensive lineman Solomon Kindley - late in the second quarter of Cincinnati's 19-7 loss Sunday in Miami, an NFL official confirmed Monday night.
On Wednesday, Williams had his suspension upheld on appeal - per a report via Twitter from NFL Network's Tom Pelissero - meaning Williams will miss Sunday's game against the Dallas Cowboys.
NFL Network's Ian Rapoport reported Monday that the participants in a fourth-quarter fight between the teams won't be suspended for their roles in the altercation, but fines will be considered.
