Passan added the player is awaiting coronavirus test results.
At least 8 people in the Philadelphia Phillies organization -- including 5 players -- have tested positive for COVID-19 this week ... and the number could continue to rise as more results come in.
A group of players and team members have been working out at the Clearwater, FL facility to prepare for the potential MLB season ... and were following strict health precautions to make sure everyone was safe, according to NBC Sports Philadelphia.
The report notes a "significant" amount of players and staffers who have been to the facility are still waiting for their results ... so the outbreak could be even worse than first thought.
