Bills add kicker Prater to active roster and change punters by signing Johnston and cutting Robbins

Kicker Matt Prater was signed to the Bills active roster off the practice squad on Tuesday, days after the 19-year veteran capped Buffalo’s season-opening comeback win over Baltimore. The Bills, however, are changing punters in preparing to play at the New York Jets on Sunday. Prater was perfect in hitting all three field-goal attempts, including a 32-yarder as time expired in helping Buffalo overcome a 15-point deficit in the final four minutes.
