In the wake of E.J. Gaines' placement on the injured reserve (groin), the Buffalo Bills announced they signed cornerback Captain Munnerlyn. The Bills also signed offensive lineman Demetrius Rhaney and defensive tackle Roderick Young.

A 10-year veteran formerly of the Carolina Panthers and Minnesota Vikings, Munnerlyn will team up with former defensive coordinator Sean McDermott in Western New York.

NFL Network's Ian Rapoport noted, via Twitter, that the Bills also worked out Coty Sensabaugh before the signing.

Munnerlyn played his last two campaigns in Carolina, his second stint with the team. Previously, he played under McDermott for three seasons before McDermott left for the head-coaching job in Buffalo in 2017.

A seventh-round pick in 2009 by the Panthers out of South Carolina, Munnerlyn has carved out a successful career despite his draft status. He's played in 154 games, starting 85, and has recorded 522 total tackles, 64 pass deflections, and 12 interceptions.

In 2018, he played in 16 games for the Panthers, starting five. He tallied 47 total tackles, nine pass deflections, and an interception on the year.

Munnerlyn's most productive years came when McDermott was the Panthers' defensive coordinator. In their three-season span together, the cornerback started 41 games out of 46 played. He recorded 188 total tackles, 26 pass deflections, and four interceptions in that period.

Munnerlyn is the Bills' second signing of a former McDermott-staff defensive back in the last two offseasons. In 2018, they signed Rafael Bush, who retired before 2019 training camp. A defensive backs coach before his stint in Carolina, McDermott has seemed to make an impression on members of his former roster.
