Rough RB Play Situation (Full PPR)

I have Demarco Murray and Rex Burkhead on my roster, and Marshawn Lynch is sitting on waivers. Waivers won’t go through until Saturday. Right now, I have Murray as my RB2 playing tonight, but I really don’t like the matchup. Should I bench Murray in hopes that I get Lynch, with Burkhead as my backup plan, or should I just play Murray tonight?
