Ertz gathered in seven of nine targets for 41 yards during Sunday's 25-22 win at Dallas.
Ertz continues to be heavily involved in the offense since DeAndre Hopkins (knee) was lost for the rest of the regular season following Week 14. Over the past three games, Ertz has been targeted 33 times, resulting in a 21-169-0 receiving line. Ertz also led all Cardinals skill-position players not named Kyler Murray by logging 69 of 76 offensive snaps Sunday. Considering his workload, Ertz remains a viable option for Week 18, especially against a Seahawks defense that has given up 10 total touchdowns (tied for third most in the NFL) and 7.9 yards per target (ninth most) to tight ends this season.
