McKelvin makes for an interesting addition to the free-agency pool. The selection of available cornerbacks is shallow, meaning the 30-year-old defender is bound to draw interest.
McKelvin, 30, suffered through an injury-ravaged season, playing nine games after spending half the year on the team's non-football injury list with an ankle injury he suffered in 2014.
As the 11th overall pick of the 2008 draft, McKelvin started 60 games over eight seasons in Buffalo, with some of his finest work coming in 2013.
McKelvin's absence only solidifies the roles of Stephon Gilmore and second-year cover man Ronald Darby in Buffalo's secondary. Nickell Robey will provide additional support amid whispers that coach Rex Ryan could be gearing up for a reunion with free-agent corner Antonio Cromartie.
