CARDINALS PLAYER TO WATCH: WR A.J. Green. It’s not a coincidence Arizona’s late-season swoon coincided with the loss of DeAndre Hopkins to a knee injury. In the four games without Hopkins, Green is averaging three receptions for 48.5 yards. He needs to step up and make the critical plays if the Cardinals are going to advance. Green did have five catches for 67 yards and a touchdown when Arizona knocked off Los Angeles 37-20 on Oct. 3.
RAMS PLAYER TO WATCH: QB Matthew Stafford. With eight interceptions in his past four games, Stafford’s erratic finish to the season has brought back all the concerns he doesn’t have what it takes to succeed in the playoffs. But all three of Stafford’s postseason losses have been on the road, and he has never enjoyed the backing of a defense such as he has with the Rams, which is why Los Angeles went 3-1 down the stretch in spite of those turnovers. Stafford’s previous game without throwing a pick came in the December showdown with the Cardinals, when he was 23 of 30 passing for 287 yards and three touchdowns.
KEY MATCHUP: Cardinals QB Kyler Murray vs. the Rams secondary. Murray has been throwing the ball a lot without being able to push it down the field, failing to top 263 yards in any of his past four games despite attempting 41, 43, 38 and 39 passes. He will have to hit big plays against Los Angeles, which lost S Jordan Fuller to an ankle injury that will require surgery. Rams defensive backs not named Jalen Ramsey struggled mightily in the loss to the 49ers so there should be opportunities for Murray to find Green, Christian Kirk and TE Zach Ertz. Murray had two touchdowns and no interceptions in his lone win against Los Angeles in Week 4, but he has five touchdowns and six picks in his other five games against them.
KEY INJURIES: Arizona would have to make a deep playoff run for Hopkins to be able to return from his torn MCL, likely reaching the NFC championship game before he could be an option. … DE J.J. Watt (shoulder) is practicing this week to see if he can play for the first time since Oct. 24. … RB James Conner (ribs), RB Chase Edmonds (ribs/toe), DL Jordan Phillips (knee), CB Marco Wilson (shoulder) and WR Rondale Moore (ankle) are all trying to play and in the broad category of day to day. … Besides losing Fuller for the year, S Taylor Rapp sustained a concussion and CB Darious Williams hurt his shoulder last week. With Rapp’s availability a serious question mark, the Rams loaded up their practice squad with defensive backs in response, including luring two-time All-Pro S Eric Weddle out of retirement.
