Connor Barth’s missed field goal in the final seconds of a loss Sunday was the last straw of his Bears tenure. The Bears have made a change at kicker, signing Cairo Santos to a one-year deal and waiving Barth, they announced Monday. The Tribune’s Brad Biggs first reported the news. The Bears had Santos in for a workout last week, and Barth’s 11-of-16 conversion rate on field goals this season has led to his dismissal.
