The Saints activated Kelly from the reserve/COVID-19 list Wednesday, Aaron Wilson of the Houston Chronicle reports.
Kelly had resided on the list since Nov. 29, but he finally gained clearance through the league's protocols to return. Now healthy, Kelly will likely assume his role as a depth offensive lineman for the rest of the season.
Kelly was placed on the reserve/COVID-19 list Saturday, Katherine Terrell of The Athletic reports.
Kelly either tested positive for the virus or came into close contact with an infected person. He'll need to clear the league's COVID-19 protocols before returning to team activities.
