The Bears on Tuesday signed veteran defensive lineman Brent Urban and waived undrafted rookie defensive lineman Jonathan Harris.
Urban has appeared in 45 games with 19 starts over six NFL seasons with the Ravens (2014-18) and Titans (2019), recording 52 tackles and 3.5 sacks.
The 6-7, 300-pounder was selected by the Ravens in the fourth round of the 2014 draft out of Virginia. After missing his entire rookie season with a torn ACL, he sat out most of his second year with a torn biceps.
In his first NFL game on Nov. 30, 2015, Urban blocked a field-goal attempt that Ravens teammate Will Hill returned 64 yards as time expired to break a 27-27 tie and give Baltimore a 33-27 victory.
Urban started all 16 games for the Ravens last season. He signed with the Titans during the offseason and appeared in four games with them this year as a reserve before getting released earlier this week.
