Jonathan Ogden (Ravens) will announce his retirement on Thursday

OWINGS MILLS, Md. -- Jonathan Ogden will announce his retirement on Thursday, ending a stellar 12-year career with the Baltimore Ravens in which the left offensive tackle garnered 11 Pro Bowl invitations and a Super Bowl ring.

Ogden, who turns 34 next month, told friends he won't return for a 13th season. The 6-foot-9, 345-pounder has been bothered by an hyperextended toe since December 2006.

Ogden arrived at the team's training complex on Wednesday to confirm his decision and solidify plans for a news conference Thursday morning. The Ravens have called a press conference for 8:30 a.m. ET.

"I'm all right. I'm good with it," Ogden said of his retirement before meeting with team officials.

Ogden played in a career-low 11 games last year and did not participate in the Pro Bowl because of the bothersome big toe on his left foot.
