McClellan, 31, wound up signing on with the Ravens as an undrafted free agent out of Marshall back in 2010. He finished out his two-year contract with the team before signing a new three-year, $3.75 million contract last year.
McClellan stands to make base salaries of $1 million and $1.25 million over the next two years.
In 2016, McClellan appeared in all 16 games for the Ravens and recorded 55 tackles and a sack.
