Start/Sit Clement vs Powell

Was planning on starting Clement tonight but now that Crowell has missed two practices I’m stating to have second thoughts and maybe take the chance and roll with Bilal Powell if Crowell is indeed out. Clement playing tonight complicates things.

What do you all think I should do? It’s a half PPR league. A third route is leave clement in the starting lineup and if Crowell is out I could start Powell in flex position but I would be playing him over John Brown. Thoughts??
