Dan Quinn: No concern about Julio Jones (back)

FLOWERY BRANCH, Ga. -- Atlanta Falcons coach Dan Quinn said Julio Jones probably will be limited at practice after suffering a back injury in Detroit, but Quinn expressed no concern about Jones' status for Sunday's matchup with Buffalo.

"He'll likely get a good bit of work as we get through the week," Quinn said.

Quinn was asked if it's safe to assume Jones will be ready to face the Bills.

"Correct," Quinn said.

Jones suffered the injury on the Falcons' last offensive play of Sunday's 30-26 win over the Lions. He was flipped in the air by Lions safety Glover Quin while running after the catch and then dove after a ball Jones thought might have been jarred loose from him.

Jones said after the game he would have returned to action had the Falcons converted on third down.

"I'm good," Jones told ESPN. "If we would have gotten the first down, I would have been in there. Yeah, I'm good."

In other injury news, Quinn said starting free safety Ricardo Allen is in the concussion protocol after delivering a hit with two minutes remaining in the game. He was replaced by rookie Damontae Kazee, which probably would be the same case if Allen is unable to go against the Bills. Kazee played 18 defensive snaps against the Lions.

"If he's called upon, he's ready," Quinn said. "We really trust where he's at in the process. He really doesn't feel like a guy transitioning to safety any longer."

Quinn also remains "optimistic" about right tackle Ryan Schraeder returning from a concussion by Sunday. Schraeder remains in the protocol after sustaining the concussion in the win over Green Bay. He missed the Lions game and was replaced by Ty Sambrailo.

As for Sambrailo, Quinn offered an assessment of his first start as a Falcon.

"What did I like about Sambrailo? I liked that there was urgency in the way that he would cut," Quinn said. "I think he improved from the performance before (vs. Packers). And I think the issues that came up on the sacks were things that we could clean up on, where we can get our hands tighter and get a better punch. But I thought in the run game, I really felt his presence. That was a real factor in this game."

Quinn said he had no update on the status of pass-rusher Vic Beasley Jr., who suffered a hamstring strain against the Packers. Beasley was expected to be sidelined a month, but Quinn refused to put a timeline on the recovery. Quinn also had no update on defensive lineman Courtney Upshaw, who missed the Lions game with an ankle injury.

"We'll still see where we're at with Beasley and Upshaw," Quinn said. "We'll see where they look for this week as their both going. Both of them have worked hard to come through."
