The Texans signed guard Keaton Sutherland, who they previously had waived on Aug. 18.
As a corresponding move, Houston placed undrafted free agent tackle Kilian Zierer on injured reserve. The Auburn product left late in the second quarter of the 28-3 loss to the Miami Dolphins.
Zierer saw considerable time playing tackle for the Texans in preseason with 79 snaps along with two special teams snaps. Zierer had been with the Texans since rookie minicamp.
