Kyren Williams Limited with Ankle Injury, Rams Backfield Watch

Rams RB Kyren Williams (ankle) is listed as limited on Wednesday's practice estimate. He looked to get banged up briefly during Monday's game but re-entered and handled a vast majority of snaps after halftime. The Rams are expected to use starters Week 18 against Arizona, but there'd still be some risk of Ronnie Rivers taking over the backfield as the game progresses.
