This is tough news to hear as a pats fan. Rob ninkovich is a good player and even better guy. I never would’ve expected to hear this. This is a blow for the Pats D as it looks like Barkevious Mingo and Chris Long will be the starters on the edge. Ninkovich is a great edge rusher but I believe the Pats can overcome this. Mingo has looked to be a great pickup. In last nights game his speed was his asset, and was just blowing by guys. If he can keep this up he will cause lots of holding calls on opposing offensive lines. Chris Long on the other side has also been performing well. It seems Long is using his strength, especially his arms to blow by defenders. Also with Jamie Collins, and Donta Hightower at Linebackers, and Devin Mccourty and Malcom Butler as defensive backs I think the Patriots will be just fine. Also for all we know this could be another ploy by Roger Goodell to stop Tom Brady and the Patriots from winning their 5th title.
