Jean-Francois was released by Washington earlier this week. He’s an eight-year veteran who played the last two seasons in Washington and previously played for the 49ers and Colts.
Brown, a second-round pick of the Ravens in 2013, has never been a starter. He played in 12 games for the Jaguars and two for the Jets last season after being cut by the Ravens in September. Brown has played in 48 games over his four-year career.
