Kirksey was activated from the reserve/COVID-19 list Saturday, Aaron Wilson of Sportstalk 790 Houston reports.
Kirksey's return will be a boost to the Texans' defense after he missed their Week 15 matchup with Jacksonville. The veteran has barely missed a snap this season when healthy, recording 73 tackles (44 solo), six passes defensed, two fumble recoveries and an interception in 10 games. He'll look to add to those numbers Sunday against the Chargers.
