The Buffalo News was first to report on Byrd's status.
It's unknown at this time when Byrd might show up. Byrd is the only franchise-tagged player who has yet to sign his tender. The tag is worth $6.9 million.
Byrd reportedly is looking for a deal that would make him the highest-paid safety in football. The Bills would like to keep him in Buffalo, but they believe his value falls somewhere in the top five salaries of the position.
Rapoport additionally reported that the Bills might trade Byrd. He'd have to consent by signing his franchise tag for that to happen. Because the deadline has passed for tagged players to sign a long-term contract, there can be no financial gain for Byrd.
Since Byrd is not under contract, the Bills cannot fine him for missing camp time. The likely scenario to play out is Byrd signs his tender shortly before the start of the regular season. Byrd might be disgruntled, but don't expect him to pass on game checks.
