Analysis:

Concern is mounting in regard to Avila, who will sit Friday for a fourth straight game and for the eighth time this month. Avila took yet another foul ball off his facemask last Sunday, and a possible return date will remain up in the air until his symptoms subside. The 27-year-old has dealt with concussions each of the past three seasons, but the team still has not labeled his current injury a concussion.
