EARTH CITY, Mo. -- The St. Louis Rams made a small roster tweak Tuesday evening, adding another body at tight end and cutting ties with a wide receiver.

On his way out is Damian Williams, the veteran wideout the Rams signed a few weeks ago. Williams played one game for the Rams but had been inactive the past couple weeks because of a hamstring injury.

Tight end Justice Cunningham replaced Williams on the active roster, earning the promotion from the practice squad. Cunningham had received interest from another team looking to add him to its active roster, but the Rams made the move to help prevent Cunningham from leaving.

With the addition of Cunningham and subtraction of Williams, the Rams now have five tight ends and four receivers on the 53-man roster. The five tight ends -- Jared Cook, Lance Kendricks, Cory Harkey, Alex Bayer and Cunningham -- comprise the same group that made the team's initial 53-man roster out of training camp.

The Rams will have to make another roster move this week to add defensive end Chris Long to the roster from the injured reserve/designated to return list. Long has been practicing the past two weeks, and it's expected he'll be ready to go this week against the Oakland Raiders, barring a setback.
