Greene’s exit comes after he appeared in 25 games, with six starts, in the past two seasons, when he collected 60.5 tackles, an interception and a forced fumble. The Bears selected Greene in the fourth round in 2013 draft, and many lauded his potential before his inconsistent play.

Devlin, Williams and Woestmann have latched on to the Bears after being tryout players at rookie mini-camp over the weekend.
