I doubt they leave Burnett off, I know he's had his struggles/sore elbow of late, but I think he was more snakebit than anything his last couple of outings.
And you've go to have Lannon on the roster, I think it's very, very risky to go into the post season with only 4 starters, what if a starter (God Forbid, knock wood) gets injured? You going to have Big Sexy start instead?
