Ball (ankle) was activated from the reserve/COVID-19 list Wednesday, Aaron Wilson of Sportstalk 790 Houston reports.
The offensive lineman missed the Cowboys' regular-season finale in Week 18 after being placed on the COVID list Jan. 4. Assuming he's also clear of his ankle injury, Ball may return to the team in time to provide a depth option at right tackle heading into the Cowboys' wild-card game against the 49ers on Sunday.
