Baltimore Ravens QB Lamar Jackson, 24, tests positive for COVID-19 for a second time and could miss 10 days if it's revealed he STILL isn't vaccinated

Former NFL Most Valuable Player Lamar Jackson has tested positive for COVID-19 for a second time and consequently missed Baltimore's first practice of training camp.

Jackson missed one game last season, in Week 12, when he first tested positive for the novel coronavirus. It's not known if he's been vaccinated since then, but if he hasn't been, Jackson will need to quarantine for 10 days and test negative for COVID-19 before he can return. 

Ravens coach John Harbaugh announced Jackson's positive test after practice Wednesday and said running back Gus Edwards also tested positive. He would not go into much more detail about either case or whether either player was vaccinated.

'It's just part of the deal. It's just the way the world is right now,' Harbaugh said. 'We have 90 percent vaccinated, and I think we're going to go above that, too, real soon here. So we're in really great shape with the vaccinations.' 

Jackson previously declined to answer questions about whether he's been vaccinated. 

'Just like everyone in society, it's their decision, keeping that to themselves,' Jackson said in June. 'But I feel we do a great job here of taking the vaccine, staying away from COVID, following the right preparation and stuff like that, staying away from the outside to the people that are attracting it.' 

Baltimore Ravens running back Gus Edwards also tested positive for COVID-19

Jackson, who won MVP honors in 2019, is entering his fourth season with Baltimore. He threw for 2,757 yards with 26 touchdowns and nine interceptions last season. He's also rushed for over 1,000 yards in each of the past two seasons.

Baltimore won a playoff game with Jackson for the first time last season, but the Ravens were then eliminated at Buffalo.

Edwards signed a contract extension through 2023 this offseason. He ran for 723 yards last season, helping the Ravens rank first in the NFL in rushing for a second consecutive year.

Last week, the NFL announced that 80 percent of players have started the vaccination process and that 27 of 32 teams had at least 70 percent of players either receive one vaccination shot or both. 

While players are only encouraged - and not required - to get vaccinated, coaches, scouts, equipment managers and team executives must be fully vaccinated in order to work in the NFL.

Minnesota Vikings assistant coach Rick Dennison will remain with the team in a new role despite his decision not to receive the COVID-19 vaccine, in violation of NFL rules

That was a problem with the Vikings this week after offensive line coach Rick Dennison was reportedly on his way out of Minnesota after refusing to to be vaccinated.

ESPN reported Friday that Dennison, an offensive line coach and running game coordinator, stepped down, becoming the first position coach to leave a team because of vaccine guidelines.

The team, however, told DailyMail.com that Dennison remained an employee.

The two sides found a compromise on Tuesday, when the team announced that Dennison would serve as an offensive advisor this season.

For now, all of his collaboration with the staff must be virtual. He'll help the other offensive assistants evaluate players and devise game plans, as in the past, but he won't be able to have the hands-on work with the offensive linemen he's drawn praise for throughout his years in the NFL.

The New England Patriots and assistant Cole Popovich could not come to a similar agreement, and the co-offensive line coach will be leaving the team over the NFL's vaccination policy, according to multiple reports.
