Kelly will compete with Justin Davis for snaps as the Rams' backup running back while Malcolm Brown (clavicle) is unavailable, Gary Klein of the Los Angeles Times reports.
A rookie sixth-round pick, Kelly has been a healthy scratch all season while Davis has strictly played special teams. Kelly was more impressive of the two during the exhibition slate, but Davis has the advantage of being in his second year with the Rams. Of course, Brown's indefinite absence doesn't have much impact on the game plan for Week 14 in Chicago, seeing as Todd Gurley has played 85 percent of the offensive snaps this season. It could come into play Week 17 if the Rams don't have anything to play for and decide to rest key players.
