The Buffalo Bills were unable to reach a long-term agreement with Jairus Byrd ahead of the 2013 NFL season.

The safety had until yesterday afternoon to sign a multi-season contract with the team, having been placed under the franchise tag earlier this year.

Bills general manager Doug Whaley told the team's website: "We worked very hard to come to a long-term agreement with Jairus, but unfortunately were unable to reach one before [yesterday's] deadline.

"Our attention will now be focused on a one-year agreement with him and on training camp with our continued efforts to prepare our team for the upcoming season."

The Bills will now not be able to finalise a contract extension with Byrd until the end of the 2013 regular season.
