Firkser didn't draw a target in Sunday's 41-34 loss to the Rams.
Firkser saw his offensive snap count drop from 35 to 22 in Week 15 with Shane Zylstra returning from a knee injury that forced him to miss 11 contests. Firkser has now caught both of his targets for 11 yards while playing 75 snaps on offense over four games with Detroit this year, and he has little to no fantasy utility moving forward.
