Ravens offensive tackle Adam Terry is headed to Injured Reserve because of a right knee injury that will require surgery.
Terry said the surgery, which could be a microfracture procedure, is scheduled for next Tuesday.
It will be the Ravens' second consecutive year that a key player has undergone microfracture surgery after defensive tackle Kelly Gregg had it last fall. That was following a previous arthroscopic surgery to clean out Gregg's knee in training camp did not fully heal.
By all accounts, Gregg has made a full recovery, as the stalwart nose guard has seen no ill effects in training camp.
The Ravens hope to see the same results with Terry.
"It's along the lines of a Kelly Gregg thing," said head coach John Harbaugh. "With Kelly, we thought he would be OK when he had the first procedure, but it didn't heal. There were some cartilage issues in there, and it should be fine this year. Once the surgery is done, it takes some time for that cartilage to grow back in.
"Adam should be no problem for next year."
Terry underwent arthroscopic knee surgery earlier this offseason and was limited throughout all Organized Team Activities (OTAs). He began training camp on the Physically Unable to Perform list.
Terry watched the Ravens' first two days of training camp from the sideline, but he remained in McDaniel College's Gill Gymnasium for the rest of the practices with his entire right leg tightly wrapped in a bandage or compression sleeve.
He was originally slated to challenge rookie Michael Oher for the starting spot at right tackle.
Baltimore worked out two players on Tuesday and will sign one pending a physical.
