Armstead noted in a tweet that he feels "completely normal and ready to go play" but will not be permitted to do so (Warning: Some language NSFW):
T. Stead 🎤🎧 @T_Armstead72
Found out this morning that I tested positive for Covid! I feel completely normal and ready to go play with my guys tomorrow. Unfortunately that can’t happen and while that shit sucks, I can’t downplay the impact covid has had on so many lives. Everyone stay safe 🙌🏾 #WhoDat ⚜️
The Saints will put their 8-2 record on the line Sunday when they face the 4-6 Broncos on the road at Empower Field at Mile High in Denver.
Armstead, 29, is in his eighth season and has developed into one of the NFL's best left tackles since the Saints took him in the third round of the 2013 NFL draft out of Arkansas-Pine Bluff.
He was named a Pro Bowler in both 2018 and 2019 is well on his way to a third consecutive Pro Bowl nod this season thanks largely to the lanes he has opened for running back Alvin Kamara.
Armstead has started 81 of the 85 regular-season games he has appeared in, and replacing him Sunday will be no easy task.
The fact that left guard Andrus Peat is also out for Sunday's game because of a concussion will put New Orleans in an even tougher position, especially with inexperienced quarterback Taysom Hill starting over the injured Drew Brees (ribs).
Former Baltimore Ravens offensive lineman James Hurst is listed as the backup left tackle on the Saints' depth chart and could be in line to start, although he also has experience starting at left guard.
Hurst has appeared in 96 career regular-season games, making 46 starts. If Hurst starts at left guard instead, undrafted rookie Ethan Greenidge could be an option at left tackle.
Armstead is not the only player to be impacted by COVID-19 entering Sunday's game, as the Broncos placed both backup quarterback Jeff Driskel and wide receiver Diontae Spencer on the reserve/COVID-19 list this week.
Two Broncos staffers tested positive for COVID-19 as well.
The game is still scheduled to be played Sunday at 4:05 p.m. ET, although the COVID-19 pandemic has already caused one game to be rescheduled this week, as the Pittsburgh Steelers vs. Baltimore Ravens game was moved from Thanksgiving to Sunday and then to Tuesday night.
