Rams head coach Sean McVay said Kupp will be limited in Thursday's walk-through practice due to a toe injury, Lindsey Thiry of ESPN.com reports.
Kupp will make his first appearance on the injury report all season, as he's otherwise either been a full participant in every practice or sat out for rest purposes through the first 13 weeks of the season. The fifth-year wideout didn't show any obvious sign of being hurt in the Rams' Week 13 win over the Jaguars, rolling to his seventh 100-plus-yard receiving outing in Los Angeles' 37-7 win. So long as Kupp maintains limited activity or upgrades to full participation Friday and/or Saturday, he'll likely be in little danger of missing Monday's game against the Cardinals.
