The Ravens have very little room under the salary cap and evidently won't be spending the money it will take to keep Smith in Baltimore when free agency begins on Tuesday.
In a blog, Smith wrote Sunday, ''I will be playing for a different organization'' and ''It is tough to leave a city that I now call home.''
Smith is the Ravens career leader in yards per catch with a 16.9 average. He ranks second in team history with 30 touchdown catches.
Smith had 49 catches for 767 yards and 11 TDs in 2014. Various reports indicate he will be signed this week by San Francisco.
