FLOWERY BRANCH, Ga. -- Atlanta Falcons coach Dan Quinn said left tackle Jake Matthews and outside linebacker Brooks Reed have been ruled out for Thursday's final preseason game against the Baltimore Ravens because of injuries.

Reed, who has been dealing with groin and hip injuries since signing a free-agent contract with the Falcons this offseason, is supposed to get a second opinion on his latest groin injury. Quinn said the second option will determine if surgery is necessary, although the team is not ready to go that route just yet. Reed initially said he didn't need surgery.

"We certainly are concerned," Quinn said of Reed's injury. "So we're just trying to get it right in terms of him getting the strength back to feel like it's just in the right spot. ... He's got such a toughness and edge-setting pressure. We're just trying to get him where he's feeling at his best."

Reed, who last played with the Houston Texans, signed a five-year, free-agent deal that included $9 million guaranteed. If he has groin surgery, that could jeopardize his season, depending on the severity. Fellow newcomer O'Brien Schofield is listed as the backup at strongside linebacker behind Reed.

As for Matthews, Quinn addressed the back situation.

"I'm not going to go there until they tell me to," Quinn said. "We always have, 'OK, what could be down the road?' But I'm more the other way like, 'He's going to be good,' until he's not."

Quinn did not rule out any other player for Thursday night, although wide receiver Roddy White won't play and is still on the mend following arthroscopic surgery on his right elbow. White is expected to resume some type of activity next week with padding protecting the elbow.

Running back Devonta Freeman, who has yet to play in a preseason game after straining his right hamstring the first week of training camp, is unlikely to play Thursday night as well. Freeman continues to experience a little pain when he attempts to cut, although he's participated in practice this week.

Also sidelined during Tuesday's practice were wide receiver/return specialist Devin Hester (turf toe), linebacker Justin Durant (foot), tight end Tony Moeaki (ankle), and running back Antone Smith (hamstring), among others. Linebacker Joplo Bartu (quad) had a helmet on at the start of practice, then went over to a side field for exercises with the athletic performance staff.

Also, the Falcons made their 75-man roster limit by the 4 p.m. deadline by reaching an injury settlement with former second-round pick Peter Konz, a center/guard out of Wisconsin. Konz, who recently had knee surgery and was placed on IR last year with an ACL tear, started 28 games in three seasons with the club.

Konz was in the final year of his contract and due a base salary of $879,345 this season.
