The New England Patriots have signed veteran cornerback Tarell Brown to a one-year contract, according to a league source. Brown visited the Patriots twice this offseason. Brown, 30, was still available for this late in the offseason primarily for health-related reasons. He played through a broken foot last season with the Raiders, starting 14 games and recording 55 tackles, no interceptions and four passes defended. Brown played last season in Oakland under a one-year, $3.5 million contract.
