Jairus Byrd has plantar fasciitis

ORCHARD PARK, N.Y. -- Jairus Byrd's availability for the Buffalo Bills' season opener against the New England Patriots is uncertain, coach Doug Marrone said Sunday, due to a foot injury the safety revealed is plantar fasciitis.

"Same thing Mario [Williams] had, it's called plantar fasciitis," Byrd told reporters in the locker room Sunday, according to the team's official website. "It's just a little foot condition. We'll see how it goes."

Byrd participated in only a portion of team drills during Sunday's practice, according to Marrone, who added that he did not know if Byrd will play next Sunday.

"I need to be good to go before I step out there," Byrd told reporters. "Once my body allows me to be out there and be at 100 percent ready to play, I'll go."

The Pro Bowl safety sat out all of training camp, declining to sign his franchise tender until the Bills were set to return to their facility. Byrd did not play in the final two preseason games.

After Thursday night's preseason finale, Marrone said Byrd left the team to see foot specialist Dr. Robert Anderson in North Carolina, the same doctor that Williams visited at the start of training camp. Anderson confirmed the plantar fasciitis diagnosis and said it would be difficult to play through, a source told ESPN NFL Insider Adam Schefter.

If Byrd cannot play Sunday against New England, expect the Bills to again turn to Da'Norris Searcy and Aaron Williams as their starting safeties.
