Alexander Mattison – Running Back – Minnesota Vikings (34% rostered) Regarded as one of the best handcuffs in the league, Alexander Mattison is this week’s top priority add after Dalvin Cook went down with a painful shoulder injury. Early reports say he dislocated his shoulder, and with how much pain he was in it wouldn’t be crazy to hear that it was worse than just a dislocated shoulder. Cook will undergo tests to see if there is any further damage to the area. That said, it’s safe to say Cook probably at least misses one week, and with fantasy playoffs coming up Mattison isn’t a bad player to roster regardless of Cook’s status. FAAB: Everything if news comes out that Cook will miss extended time.
