Cook and McGovern were both voted as first alternates back in Week 18. Starting left tackle Dion Dawkins and quarterback Josh Allen were the lone two Bills to earn spots on the AFC's initial Pro Bowl roster. Allen likely will forego the opportunity after injuring his wrist during the AFC Championship Game loss to Kansas City on January 26.

Cook fills the spot left open by Baltimore’s Derrick Henry, who finished second in the NFL with an AFC-leading 1,921 yards rushing. Cook had 1,009 yards rushing with 16 touchdowns, tying Henry and Detroit’s Jahmyr Gibbs for the league lead.
