Should I be worried about my injury prone QBs?

QBs: Bulger and Leftwich. The season hasnt even started yet and both are healthy so far, but how worried should I be about this pair? Should I shop for another QB and who should I look to replace? I have great depth at RB (LT, FWP, Mike Bell, Thomas Jones), so I could trade one of them (except LT), but what could I get for them in terms of a QB upgrade or dependable backup?

There is always a qb or two in the free agent pool that plays way better than expected, Keep an eye out for him and you will be just fine...
