Allen (back) was a limited participant in practice Wednesday, Rich Cimini of ESPN.com reports.
Allen's ability to practice in any capacity is a good sign after he was unable to finish this past Sunday's 32-25 win over the Jaguars. Fellow backup running back Isaiah Davis (back) was also limited Wednesday, while Breece Hall practiced without limitations. Now that Hall seems to be over the knee injury that cost him Week 14 and likely played a factor in his limited workload Week 15, Allen and Davis could both see only light touches even if they play Sunday against the Rams.
