Harris tested positive for COVID-19 and has been placed on the Cardinals' reserve/COVID-19 list, Aaron Wilson of Sportstalk 790 Houston reports.
Harris was expected to see a larger role after Maxx Williams (knee) was placed on IR with a season-ending injury. Instead, the Cardinals acquired Zach Ertz and Harris has remained limited. Expect Harris to miss at least this week, with his next chance to see the field likely being in Week 10 against the Panthers.
