Allen was listed as a non-participant Wednesday on the Rams' estimated injury report due to a foot injury, Sarah Barshop of ESPN.com reports.
Analysis:Allen reeled in both of his targets for 24 yards during Monday's 37-34 overtime loss to the Bills, and he may have picked up the foot injury at some point along the way. The 25-year-old will have two more chances to practice prior to Sunday's contest versus Arizona.
