Yes, but like you read also, it says clearly in the same article that the same players who give a positive (traditional) covid test, can still return to the game. Reads right in the article. Interesting to me. Better quote the whole post next time sire.
Here: "
In creating the new return-to-play protocols, the NFL and NFLPA focused on a new metric that measures the viral load of a player, known as the "cycle threshold" (CT). In essence, the CT value can measure whether a player is still contagious, even if in some cases he would still test positive on a traditional test.
That testing can begin as soon as one day after the initial positive and could significantly shorten the amount of time a vaccinated player spends away from the team facility."
