Former Dallas Cowboy Michael Irvin is facing accusations he assaulted a disabled contractor who was hired to install a fountain at his Plano home.

Shawn Vandergrift filed a lawsuit Monday against Irvin in Denton County, claiming that the former player yelled at him and grabbed him during a December dispute over a final payment for the construction work.

The suit claims that Vandergrift is permanently disabled by a hip condition and that he required medical attention as a result of being grabbed on the left arm during the confrontation.

Irvin could not be reached for comment Monday night.
