(ALLEN PARK, MI) – Detroit Lions quarterback Matthew Stafford was removed from the reserve/COVID-19 list Tuesday and placed on the active roster after what the team called a false positive test. Stafford appeared Saturday on the reserve/COVID-19 list, which means a player either has taken a test that has come back positive or has been in close contact with someone who has been diagnosed with the coronavirus. The Lions, in a statement released Tuesday, said Stafford never had COVID-19 and instead had a false positive test after two negative coronavirus tests last Tuesday and Wednesday. On Friday, Stafford took a test that came back positive on Saturday. His following three tests were all negative and everyone in his family has been tested and they are all negative. Stafford was the first starting quarterback to go on the reserve/COVID-19 list and, at the time, the eighth Detroit player. Since then, tight end Isaac Nauta, starting slot corner Justin Coleman and Stafford have been removed from the list, leaving T.J. Hockenson, Kenny Golladay, Jalen Elliott, Arryn Siposs and Amani Oruwariye still on the list. The Lions are paying attention to false positive tests because they could cause a player to miss a game if they occur during the regular season.
