Parker (shoulder/hamstring) wasn't spotted at Thursday's practice, David Furones of the South Florida Sun Sentinel reports.
With that, Parker's status for Sunday's game against the Jaguars in London is cloudy. Friday's injury report will reveal the wideout's chances of suiting up Week 6, but if Parker is out or limited versus Jacksonville, Preston Williams likely would be in store for a heightened role in the Miami passing attack along with Jaylen Waddle, Mike Gesicki and Myles Gaskin.
