Should I drop L Murray

Should I drop latavius Murray for Jordan Matthews? I’m in a PPR League.
Current roster
Qb-Kirk cousins
RB- Todd gurley
RB- Doug Martin
WR- AJ Green
WR- Alshon Jeffery
TE- Evan Engram
Flex- James white
Marvin Jones jr
Javarus Allen
Austin hooper
Latavius Murray
Sterling Shepard
Darren McFadden

I think you could drop Murray for someone else maybe but I would not have that person be Jordan Matthews. He will more than likely miss week 7 still recovering from his thumb surgery. in a PPR setup he is only pulling in like 3 targets a game. Who else @ WR is available ?
