The Bears on Saturday activated tackle Larry Borom off injured reserve and elevated tackle Jake Curhan and cornerback Reddy Steward from the practice squad to the 53-man roster.
The moves were made in advance of Sunday's game against the Cardinals in Arizona.
Borom has not played in a regular-season game this year after injuring his ankle in the preseason finale against the Chiefs. The 2021 fifth-round pick from Missouri appeared in 39 contests with 23 starts in his first three seasons with the Bears.
Curhan signed with the Bears this year after spending his first three NFL seasons with the Seahawks, playing in 29 games with nine starts. Curhan's offensive coordinator in Seattle was Shane Waldron, who is in his first year in the same role with the Bears.
Steward signed with the Bears in May as an undrafted free agent from Troy. In the preseason finale in Kansas City, he registered two interceptions, returning one for a touchdown.
