Davis (ankle) was placed on injured reserve Wednesday, Aaron Wilson of Sportstalk 790 Houston reports.
Davis was ruled out for the remainder of the season after suffering a fractured left ankle in Sunday's loss to the Seahawks. He'll undergo surgery to address the injury, and it's unclear if he'll be back to full strength by the spring. The 25-year-old receiver appeared in two games for Houston this season, recording one reception for 17 yards on three targets across 20 snaps on offense.
