Although no deal is imminent at this time, the Ravens are expected to revisit the talks with agent Jimmy Sexton going forward.
"We've had some preliminary discussions with his agent," Ravens general manager Ozzie Newsome said.
Oher, 26, is under contract through the 2013 season.
He's signed to his original five-year rookie deal worth $12.799 million, which included $7.82 million in guaranteed money.
Having started 55 regular-season games, plus six playoff games, since arriving in Baltimore in 2009 when the Ravens drafted him in the first round with the 23rd overall pick, Oher said he would like to stay with the defending AFC North champions for the remainder of his career.
"I love it here," Oher told The Baltimore Sun. "It's a great organization, great city. I would love to finish out here. That's up to the organization. Without a doubt my ears are open."
Oher returned to left tackle this season after starting at right tackle last season, where he primarily lined up as a rookie.
The 6-foot-4, 315-pounder from Ole Miss is due a $3.085 million base salary next season after triggering a $2.1 million escalator clause through his performance from 2009 to 2011.
Oher has shifted back and forth from right tackle to left tackle, lining up at right tackle for 11 starts and left tackle for five starts as a rookie.
Two seasons ago, Oher started every game at left tackle.
This season, Oher has allowed two sacks and 13 quarterback pressures with four penalties through seven games as Baltimore (5-2) is in first place in the AFC North.
"Michael Oher is doing a good job and always works really hard," Pro Bowl offensive guard Marshal Yanda said. "He's a great player. He's what you want in a football player. He takes it seriously, he works hard. He works at his craft every day in practice and he's just a great guy."
The Ravens have a history of retaining their own players, including signing Yanda to a five-year, $32 million extension two years ago that included $10 million in guaranteed money.
"Obviously, we want Mike to stay," Yanda said. "Hopefully, everything works out. You have to deal with the business side. It would be great to have him here long term because he's a great teammate, a great player and a guy you like to play with on Sunday.
"He gives it 110 percent. There's no B.S., no nothing. He puts his life into this thing just like I do. You want more guys like that."Copyright © 2015, The Baltimore Sun
