All eight Vikings players who missed Sunday’s practice because of presumptive positive COVID-19 tests were back on Monday, as the NFL said it had gotten to the root of the problem that produced 77 false positive tests among players, coaches and team staffers over the weekend.
BioReference Laboratories, the company handling the NFL’s coronavirus testing program, said in a Monday statement that an investigation indicated the positive results were “most likely” erroneous and blamed them on contamination in a New Jersey laboratory.
“I do believe the problem has been corrected,” Dr. Allen Sills, the NFL’s chief medical officer, said in a conference call on Monday.
