Barth, 30, originally signed on with the Chiefs as an undrafted free agent out of North Carolina back in 2008. He spent just over a year in Kansas before he was cut loose.
After a brief stint with the Dolphins, the Buccaneers signed him to a contract back in 2009 and later returned to the team on a two-year deal last season. However, he was released in May of last year. The Saints signed him to a contract a month later, but he was unfortunately among their roster cuts.
After the Bears moved on from Robbie Gould, Barth was signed to a one-year deal.
In 2016, Barth appeared in all 16 games for the Bears and converted 18 of 23 field goal attempts (78.3 percent) to go along with 31 of 32 (96.9 percent) extra point tries and 26 touchbacks.
