INGLEWOOD, Calif. — The Los Angeles Rams spent the entire second half struggling on offense while bending just enough on defense to preserve a tiny lead.
Arizona even backed Los Angeles into its own end zone in the final minute, needing just one big play to steal a win.
Ahkello Witherspoon and the Rams hung on by their fingertips, and now they're on the brink of another NFC West title.
Witherspoon made a diving interception on a deflected pass in the end zone with 37 seconds to play, and the Rams barely maintained command of the division race with a 13-9 victory over the Cardinals on Saturday night.
Puka Nacua had 129 yards receiving and Kyren Williams scored the only touchdown for the Rams (10-6), who grinded through a difficult offensive night and survived a hair-raising fourth quarter for their fifth consecutive victory.
''We didn't do a whole lot great, to be honest with you,'' said Matthew Stafford, who passed for 189 yards in the Rams' ninth win in 11 games. ''Didn't run it great. Didn't throw it great. But found a way to get a win and get enough points.''
The Rams host Seattle (9-7) in their regular-season finale next weekend, but they could already have coach Sean McVay's fourth division title clinched before then.
If the Bills, Browns, Vikings, Commanders and 49ers combine for three wins — or two wins and a tie — over the next two days, Los Angeles will be NFC West champions based on its strength of schedule, no matter what happens against Seattle.
