Parker (hamstring/shoulder) has been downgraded to out for Sunday's game against the Buccaneers, Adam Schefter of ESPN and Daniel Oyefusi of the Miami Herald report.
With Parker slated to be inactive for Sunday's 1:00 kickoff, Jaylen Waddle, Albert Wilson and Preston Williams are in line to serve as the Dolphins' top wideouts in Week 5, with Mack Hollins and Isaiah Ford candidates to see complementary snaps.
