Players are being tested for COVID-19 several times before they are allowed to enter team facilities as they report to camp this week.

The NFLPA announced Tuesday that there have been 21 positive tests in the testing conducted as part of the training camp reporting process.

Rookies, injured players and quarterbacks were allowed to start reporting over the last week.

The union did not announce the total number of tests were done overall or whether there were any outstanding results from early tests.
