Patriots' Isaiah Mack: Moves to active roster

Mack (roster exemption) was added to New England's active roster Tuesday, Zack Cox of NESN.com reports.

The 24-year-old was claimed off waivers from the Titans last week, but he spent Week 9 on the commissioner's exempt list while going through the league's COVID-19 protocols. Mack should provide depth up front for the Patriots defense.
