His agent, Doug Hendrickson, tweeted about Boley on Tuesday morning, congratulating his client for "heading to the Bengals."
The Bengals confirmed the signing Tuesday afternoon, waiving cornerback Curtis Marsh in order to make room for Boley on the 53-man roster.
A nine-year veteran who played with the Atlanta Falcons and most recently the New York Giants, Boley tried out with the Bengals in early September as the team was attempting to shore up its depth at outside linebacker. Emmanuel Lamur had just been lost for the season with an injury and the Bengals needed help with depth behind young linebackers Rey Maualuga and Vontaze Burfict.
Boley, who played in all 16 of the Giants' games last season, not only brings another hard-hitting tackler to the mix for the Bengals, but he also brings solid coverage skills. He had 64 total tackles, three interceptions and four deflected passes in 2012.
Boley also brings some off-field baggage to Cincinnati. In May, he was charged with child abuse, marking the second time in two years that he has had to fight such a charge. While playing for the Falcons, he also was arrested on domestic violence charges in 2008. Even though the prosecutor didn't pursue those charges, Boley was suspended for the first game of the following season for violating the NFL's player conduct policy.
