WATCH: Chiefs' Branch seals a win -- and revenge -- with this Pick-Six

Oakland probably wishes it had Tyvon Branch back right about now.

Just look at what the former Raiders safety did for his new team -- the Kansas City Chiefs -- when the rivals met up at O.Co Stadium on Sunday.

That has to hurt some Raiders fans out there. Branch effectively ended their winning chances -- and maybe their playoff hopes -- with that interception return.

He spent seven years as a member of the Silver and Black. K.C. might keep him for seven more with plays like that.
