Aiyuk (hamstring) -- who did not receive a target in Sunday's win over the Lions -- fell down the depth chart due to injury and not performance, David Lombardi of The Athletic reports.

EDGE Analysis

Aiyuk was a ghost in the box score in a game during which the 49ers put up 41 points. The dynamic wideout had been nursing a hamstring injury this preseason, and while he wasn't listed on the pregame injury report, head coach Kyle Shanahan's explanation solves the mystery of why the 2020 first-round pick was not used. The rest of San Francisco's receiving corps excelled in their individual roles Sunday, but we have to assume that a talent like Aiyuk will reclaim his co-starting role alongside Deebo Samuel when he is fully healthy. For now, consider the wideout questionable heading into a Week 2 matchup against the Eagles until more information is given following practices this week.
