Byrd, who has plantar fasciitis in his feet, had been limited in practice. He was listed as doubtful for the first two games of the regular season and was not active for either contest.
This puts Byrd's shot of playing Sunday at 50-50.
Meanwhile, offensive lineman Doug Legursky was also listed a questionable after missing the first two games with a knee injury.
Cornerbacks Stephon Gilmore (fractured wrist) and Ron Brooks (fractured foot), kicker Dustin Hopkins (right groin strain), and wide receiver Marquise Goodwin (fractured hand) were all declared out for Sunday's game.
