FLOWERY BRANCH, Ga. -- Atlanta Falcons coach Dan Quinn ruled right tackle Ryan Schraeder out for the second straight week with a concussion, while All-Pro wide receiver Julio Jones -- coming off a back injury -- is probable for Sunday's game against Buffalo.
Schraeder, who entered the concussion protocol after taking an awkward head hit in Week 2 against Green Bay, was on a side field during drills the past two days. The Falcons obviously want to play it cautious, with next week's bye giving Schraeder even more time to recover.
Ty Sambrailo will get his second consecutive start in place of Schraeder. Although Sambrailo proved to be a solid run blocker in last week's 30-26 win at Detroit, he struggled some in pass protection. He figures to draw Bills defensive end Shaq Lawson, but Lawson is questionable after suffering a groin injury in practice. If Lawson can't go, then Eddie Yarbrough is listed as the backup at left defensive end.
Quinn talked this week about the challenge Sambrailo faces.
"They've got some good rushers," Quinn said of the Bills. "It's the length with Shaq when you're talking about a guy who's over 6-4 and has long arms. Those are the things as rushers. When you have length and speed, those are real factors to it.
"We know we're up for the challenge. They do have a good defensive line overall just in general. When you go through the tape over the three games this year and the preseason, it's a part of their team I've been impressed with."
As for the Falcons on offense, Jones said all week that he would be just fine to play despite tweaking his back while being flipped against the Lions. He was limited in practice but is ready to play. And he'll look for his first touchdown of the season against a Bills secondary that hasn't allowed a touchdown reception while limiting opponents to just 12.3 points per game.
Besides Schraeder, Quinn also ruled out outside linebacker Vic Beasley Jr. (hamstring), free safety Ricardo Allen (concussion), defensive lineman Courtney Upshaw (ankle/knee), and running back Terron Ward (shoulder/neck). Rookie rusher Takk McKinley once against steps into Beasley's role at left end in the nickel pass rush, and rookie Damontae Kazee will start in place of Allen.
Defensive lineman Jack Crawford will play despite being limited by a shoulder injury during the week.
