The Patriots have signed defensive lineman Ricky Jean-Francois, according to Field Yates of (on Twitter). Jean-Francois became a free agent last week when he was released by the Packers for the second time in 2017. Jean-Francois didn’t see a lot of burn in his six Packers games this year and recorded only two tackles. Last year, however, he was a seven-game starter for the Redskins and he was a full-time starter during his time with the Colts.
