Dolphins head coach Brian Flores said Parker (shoulder) won't practice Wednesday, Daniel Oyefusi of the Miami Herald reports.
Parker's shoulder injury kept him sidelined for the Week 5 loss to Tampa Bay, and he could struggle to gain clearance for Sunday's game against Jacksonville in London. With Will Fuller (finger) on injured reserve for at least two more weeks, Preston Williams and Albert Wilson will be in line to handle increased roles behind Jaylen Waddle if Parker misses another game.
