Henderson isn't on the field for the open portion of Wednesday's practice, Gary Klein of the Los Angeles Times reports.
An injury to Henderson coming out of a bye week would be the latest interesting development in a Rams backfield that remains without Cam Akers (personal) and saw rookie Kyren Williams (ankle) designated to return from injured reserve earlier Wednesday. It's possible Henderson is simply being rested or dealing with a minor injury. Regardless, the Rams will release their first Week 8 injury report later Wednesday, when the nature of Henderson's absence will be clarified.
