Duvernay didn't practice Wednesday due to a thigh injury.
Duvernay hasn't lost too many snaps since Sammy Watkins returned from injured reserve, as Watkins has mostly been quiet or else poaching some work from Rashod Bateman. That said, Duvernay has just two games with more than four targets all season, and none with more than six. Given the team's depth at wide receiver, replacing Duvernay on special teams (he returns both kicks and punts) might be the greater challenge. It isn't yet clear if he's in serious danger of missing the game in Pittsburgh this Sunday.
