Board signed a a two-year deal with the Patriots on Friday, Tom Pelissero of NFL Network reports.
Board spent last season with the Lions, where he appeared in all 17 games and registered 21 tackles (17 solo) while playing primarily on special teams. The 27-year-old should be expected to have a similar role on his new team, and while Board may not contribute much on defense, he can still provide a lot of value to New England's special-teams unit.
