According to profootballtalk.com, Losman will miss 2 weeks, and then have the bye to get back and ready for the Baltimore game. You can read the blip at http://www.profootballtalk.com/rumormill.htm
With Losman out 2 weeks, Edwards will get 2 starts. This week at home vs. the Jets and next week at home on primetime MNF against the Cowboys. It will be fun to see Edwards play, and it may help Edwards in his progression, but in no way can any Bills fan think that with Edwards at the helm he can put up points and lead us to 2 victories. That being said, if he does, and it is a HUGE "IF" it would lead many fans calling for Edwards to play even when Losman comes back.
but, I don't expect the bills to win more than this game on sunday vs. the Jets. And with the defense completely depleted, and the D-line proving it can't compete and find pressure or stop the point of attack, I can only imagine how good we will make a lot of average QB's look this year.
