Ronnie Rivers

Corum and Kyren Williams -- and in the fourth quarter, Ronnie Rivers -- were ripping off one chunk gain after another against a lifeless Cardinals defense that didn't have a whole lot of interest in tackling the hard-running LA backs. Corum blew through the Arizona front seven time and again until he ripped off a 48-yard touchdown in the third quarter without a single Cards defender laying a hand on him. Rams offensive coordinator Mike LaFleur has said he wants to keep Williams "fresh" for the postseason, meaning Corum is live for 12-15 weekly touches depending largely on game script. Corum, averaging nearly five yards per carry this season, will be a viable 12-team flex in Week 15 against Detroit.

Rams RB Kyren Williams injured an ankle in the first half of Sunday's game vs. the Panthers and is officially questionable to return. His absence will put RB Blake Corum in a feature role. RB Ronnie Rivers is also active for Los Angeles. RB Jarquez Hunter is a healthy scratch today. Update: Williams returned for the start of the second half.
