Newhouse (@MNewhouse74) tweeted Friday, saying "I appreciate the support in GB the last 4 years, such great fans and organization! Excited for the future, moving forward in Cincinnati!"
The fifth-year tackle started 16 regular season games for the Packers in 2012. He started only two games in 2013, in part due to the emergence of rookie David Bakhtiari at left tackle.
Green Bay picked Newhouse in the fifth round of the 2011 NFL draft.
