Stevenson (concussion) remained sidelined at practice Thursday, Ryan Hannable of WEEI.com reports.
Lead back Damien Harris was sidelined as well, as both he and Stevenson work their way through the NFL's concussion protocol. What Stevenson is able to do at Friday's practice will be key with regard to his chances of suiting up Sunday against the Browns. For the time being Brandon Bolden and J.J. Taylor are the Patriots' top healthy backfield options.
