Last week, the football game caused the Prime Time Line up to start two minutes late. And Fox started Futurama in Progress.
This week, the football game goes into OT, and causes The Simpsons to start five minutes late. Fox shows the episode in it's entirety.
Why should Fox give such treatment to one show over another? True, they have said this will probably be Futurama's last season, but still, it's no excuse.
