There is a report that Jon Lester received a contract extension, but the Red Sox have not confirmed that.

Boston Red Sox left-hander Jon Lester, who overcame cancer to become one of the best pitchers in the American League, has agreed to a five-year, $30 million contract extension with a $13 million team option in 2014, a source close to the team told Yahoo! Sports.

I'm sure everyone is happy for Jon at this point given his battle with cancer. The Red Sox are obviously very sure there won't be a recurrence if they are willing to commit to a long-term deal. They get a fine pitcher for a very good price.
