EDGE Analysis

Smith had popped up on the team's injury report with a back ailment during the team's final practice of the week. While his absence marked just the second time in Smith's career that he was unable to play, it's uncertain if he'll be able to return for Week 4. If not, Chaz Green figures to start once again in his place.
