WESTMINSTER -- Baltimore Ravens offensive tackle Adam Terry's season is over before it ever really began due to a chronic right knee problem that will likely need microfracture surgery to repair the damage, a condition that will force him to be placed on injured reserve.

The surgery is expected to be performed as soon as early next week, according to Terry's representatives.

"It just looks right now that he's got some new issues with the knee from a healing perspective," Raven coach John Harbaugh said. "So, he's going to have to undergo some more procedures to get that thing right. So, it looks like he's going to be out for the year."

Terry, who underwent arthroscopic knee surgery during the offseason after starting seven games last year, was expected to compete with rookie first-round pick Michael Oher for the starting right tackle job. Now, the job belongs exclusively to Oher unless he falters or gets hurt.

It's a significant blow to an offensive line in need of depth, and it prompted the Ravens to immediately work out two offensive linemen Tuesday with an eye toward signing one possibly as soon as today depending on the results of a physical.

And the Ravens are going to evaluate second-year offensive tackle Oniel Cousins as well as Joe Reitz and will deploy right guard Marshal Yanda at his old right tackle spot at times.

"Adam is bummed out," said Yanda, Terry's roommate at training camp. "We're definitely going to miss him, but you can't control injuries. Adam worked hard to get back and he's going to battle through this with a positive attitude. He's got to stay positive and we've got to move on.
 
"It's a tough deal. The mentality is, 'Next guy up.' When a guy goes down, you've got to step up and do your job. Someone will definitely do that."

Yanda is the most proven insurance policy if Oher doesn't pan out immediately. So far, Oher is off to a fast start as he makes the transition to the NFL.

"It's going to play out," Harbaugh said. "Some of these young guys need to develop, Oniel Cousins being a big part of that. Obviously, the Marshal Yanda factor helps us a lot because it adds depth as Marshal is really coming on from a health standpoint.

"But we're sure going to be looking at tackles. Now, we need another tackle in camp, at least, to be able to operate practice. From there, we'll have to see as far making the 53-man roster."

INJURY UPDATES: Tight end L.J. Smith practiced for the first time since injuring his hamstring last week, but isn't quite up to full speed yet.

"I ran a little bit," Smith said. "I didn't do everything, but I'm coming along every day. I've been improving. You just want to be careful with it. By the end of the week, hopefully I should be doing everything.

"It's a long season. I feel bad because my tight ends are out there working. I wish I could be out there, but I have to be careful because they have some packages designed with me in them and they're going to need me to be healthy."

Wide receiver Yamon Figurs returned to practice after being activated from the physically unable to perform list. Figurs had surgery this offseason after breaking his right foot.

"It feels pretty good," Figurs said. "They worked me a little bit, and they're going to ease me on in there. I'm really playing catch-up right now."

A former high school track and field star in Florida, Figurs said that he hasn't lost his speed.

"Maybe I'm even faster," Figurs said. "4.2."

Besides Terry, wide receiver Mark Clayton (left hamstring) and cornerback Samari Rolle (neck and groin), the following players didn't practice: linebackers Terrell Suggs (strained left heel), Antwan Barnes (concussion) and Brendon Ayanbadejo (toe sprain), tight end Davon Drew (right ankle), defensive tackle Lamar Divens (hip) as well as offensive tackle Stefan Rodgers and wide receivers Thomas White and Biren Ealy for undisclosed reasons.

Barnes said that he's experiencing minor headaches following the concussion suffered Sunday.

Offensive guard Ben Grubbs and tight end Edgar Jones returned to practice after leaving the field briefly for treatment.

Safety Tom Zbikowski was sidelined in the morning practice after getting hit in a sensitive area.

"I got kneed in the reproductive area," Zbikowski said. "I don't know how long it will take for me to get back out there. I'm pretty sore right now. I don't think I'll be out long. If it was a head injury, I'd be out there sooner."

QUICK HITS: Wide receiver Kelley Washington electrified and amused the crowd after catching a touchdown pass from Troy Smith by performing a convincing rendition of middle linebacker Ray Lewis' signature dance. Lewis seemed to appreciate the good-natured ribbing. ... Smith lined up at wide receiver in a red-zone drill, but didn't catch Joe Flacco's fade pass. "Troy's a football player," Harbaugh said. "I want to emphasize this again: We do a good job of moving guys around. To make too much of Troy playing receiver, we move guys back and forth all the time. I know it's a story because he's a quarterback. Troy is a quarterback. He can play, and he's throwing the ball really well."... Rookie kicker Graham Gano converted all of his field goal attempts with Steve Hauschka missing one from nearly 50 yards wide of the right goalpost. "Neither one has an edge," Harbaugh said. "They're kicking about the same, percentage-wise. They're making the most of their kicks. I think they're up around 90-plus percent. We'll see in games."... Justin Harper is emerging as a dangerous threat in the red zone, catching several lobs from Smith over the past few days.
