The Rams expect Zuerlein (quadriceps) to suit up Saturday at San Francisco, but he'll attempt kicks Friday to determine his availability, Lindsey Thiry of ESPN.com reports.
Zuerlein hasn't logged a practice rep this week due to a quad strain. Friday's test should reveal whether or not he'll be available Saturday evening, but coach Sean McVay hinted the Rams have a contingency in place in the event Zuerlein is sidelined. If that comes to pass, the Rams likely will sign Brett Maher to the 53-man roster after he had a tryout with the team, per Field Yates of ESPN.
