The Ravens have agreed to a contract extension with head coach John Harbaugh. Harbaugh's contract, a $12 million deal, is through the 2014 season, according to a source. Since his original contract was through 2011, it's a three-year extension at $4 million per year. "This is much appreciated and I am thankful to Steve [Bisciotti]," Harbaugh said. "I want to stand shoulder-to-shoulder with him, Ozzie [Newsome], Dick [Cass], our players and everyone else in the organization as we work to bring championships to Baltimore. We have a lot of great people who are Ravens. I'm proud to be part of this. We all push each other and pull together. I said it when I came here: 'It's about the team.' And, we plan to be a championship team."
