The NFL’s chief medical officer says it’s not surprising there have been positive tests for COVID-19 among players reporting to training camp.

Dr. Allen Sills notes that the disease is cutting across football just as it has through societies around the world.

Speaking on a conference call on Thursday, Sills said the league wanted to examine the results of recent COVID-19 tests before releasing the number of positives.

Players currently have to pass COVID-19 testing before they are allowed into training camp. Sills said the screening is continuing and going well.
