On Friday, they re-signed kickoff specialist Jordan Gay. No corresponding roster move has been announced (though they did say it wouldn’t be Percy Harvin).
Gay was released by Buffalo on October 7th following their Week 4 loss to the New York Giants.
In a corresponding move the Bills released safety Josh Bush.
@JoeBuscaglia: Just saw kickoff specialist Jordan Gay walking into the #Bills hotel here at The Grove. I’d expect a roster move to be coming.
