12-team, standard league

In a tie for 1st place but just found out that AJ Green, my #1 by a long shot...John Brown is my #2, may miss games.
Should I try to turn either Conner or Chubb into WR via trade? Conner may not be as valued until we know what Bell does next week so I may need to act quickly.
I could also choose to do nothing and hope that aJ returns for the playoffs.

My Other RB: Gurley, Howard, Collins
My Other WR: J. Brown, Lockett, Godwin, Parker

Thanks.
