The Bears met with Cairo Santos on Thursday and gave him a physical, according to Brad Biggs of the Chicago Tribune. As of this writing, the Bears have not signed Santos to a deal, but it is a sign that they are at least mulling a kicking change. 
Connor Barth is coming off of a strong performance in which he sank field goal attempts from 45, 44, and 49 yards in a rainy game against the Packers. However, he has been inconsistent overall this season. All in all, Barth has missed four of his 14 field goal tries, though three of those attempts were from 40-49 yards out and one was from further than 50 yards.
Santos has been on the market since being waived/injured by the Chiefs in late September. The Buccaneers reportedly wanted to sign him in October, but he was not healthy enough to play at that time.
Before getting cut loose, he converted 3-of-3 field goal tries and went 6-for-6 on extra points. He also had ten touchbacks on his 18 kickoffs. Last year, the 26-year-old sank 31 of 35 field goal tries, good for fifth in the league amongst kickers (88.6%).
Any new updates on this?
Clearly the Bears should have done more than just spoken to him
