Tuck Injury

I will need to make a lineup decision prior to the games on Sunday for my 16 team league and I have Tuck as my only DE.  Would you leave him in your lineup or add/use one of the following ... Kyle Vanden Bosch, Chris Clemons, Ray Edwards or Andre Carter?  If I pick up one of these DE's I would need to drop Weatherspoon (my 5th LB).  If you did make the move would you keep a DE2/3 on this team all year as a backup or go back to picking up a 5th LB.  We start 2 LB's, 1 DE and 1 flex.

I would carry a backup DE throughout the year. I'd pick up Ray Edwards.
