Manhertz (illness) was activated from the reserve/COVID-19 list Saturday.
Manhertz landed on the COVID-19 list Monday after testing positive for the virus, but he was able to clear the protocols and will be available for Sunday's matchup with New England. The 29-year-old is poised to operate as the Jags' No. 1 tight end since James O'Shaughnessy is sidelined by a hip injury.
