Metcalf had a minor scope on his knee about a week ago but seems to have a shot to play in Week 1. There isn't really a sure thing behind Lockett at this point, so if Metcalf plays he still comes with risks but could certainly see some targets. Moore has a broken arm and also is a big question for Week 1, leaving Brown and Ursua up next.
SEA WR David Moore - Week 5 Fantasy Football Outlook
Week 5 vs Los Angeles Rams
In his two games since returning from injury, David Moore has four targets and two catches. He is the Seahawks third receiver but has zero fantasy relevance right now as he is getting on the field 30% of the snaps. No reason for him to be on a fantasy roster at this point.
