This is the biggest news coming out of the injury report this week along with the DE Ray Williams not practicing at all as well. I have Harvin being the most dangerous person for the Saints to defend and could be a huge factor if the Vikings are to do anything offensively vs Gregg Williams' aggressive defense. Harvin had to miss a game recently because the headaches would not subside. For a rookie like Harvin to miss practice like this is already significant. He needs to have the reps and missing them is not good for the Vikings.
