Week 5 RB/FLEX help

Have Melvin Gordon, Ty Montgomery, James White and Doug Martin. Gordon locked in this week but with montys injury should i play white and martin in my rb2 and flex spots? or would tyrell williams or rishard matthews be a better flex option? also have aaron jones just in case.
Help greatly appreciated!!

I like aaron jones and martin this week but PLEASE monitor those pesky greenbay rbs
