Cousins (ribs) was a full practice participant Thursday, Craig Peters of the Vikings' official site reports.
One day removed from logging a rare limited session Wednesday due to a rib issue, Cousins handled every practice rep thrown his way. The Vikings took a hit in the skill positions Thursday when Dalvin Cook (illness) tested positive for COVID-19, while Adam Thielen (ankle) managed a second consecutive LP on the team's injury report. There's a distinct possibility Cousins could be without both Cook -- who won't play Sunday -- and Thielen this weekend against the Rams, leaving Justin Jefferson, Alexander Mattison, K.J. Osborn and Tyler Conklin as his top options on offense.
