The Miami Dolphins may be without their starting left tackle in the 2021 season opener.

As the team announced Monday, tackle Austin Jackson and tight end Adam Shaheen have been placed on the reserve/COVID-19 list, with just six days to go before they head to Foxborough for a Week 1 matchup with the Patriots. Per Mike Florio of Pro Football Talk, a league memo indicated that both Jackson and Shaheen returned positive tests.

Shaheen won’t be available for the Dolphins, due to being unvaccinated. Shaheen recently said the NFL is “not going to strongarm me” into getting vaccinated, but also that he planned to “comply with protocols,” via Outkick’s Armando Salguero. Per league rules, unvaccinated players who test positive need to be away from their teams for a minimum of 10 days.

If Jackson is vaccinated, he can rejoin the Dolphins once he returns two negative COVID tests separated by a 24-hour span. So, until otherwise reported, Jackson has a chance to be back in the Dolphins’ lineup Sunday afternoon. A first-round pick in the 2020 draft, Jackson is coming off a rookie season in which he played 13 games at left tackle, starting 12.

The Dolphins and Patriots square off at Gillette Stadium on Sunday at 4:25 p.m. ET to kick off the 2021 regular season.
