The Kansas City Chiefs remained without All-Pro safety Tyrann Mathieu after his positive test for COVID-19 as the two-time defending AFC champions began preparing Monday for their season opener against the Cleveland Browns.
Chiefs coach Andy Reid said that Mathieu, who was vaccinated against the virus, remained in the league’s protocol, which means he had yet to return two negative tests taken 24 hours apart. That is the requirement for vaccinated players who are asymptomatic to return to their teams under the NFL rules released in July.
The Chiefs were off Tuesday before returning for their first on-field work of game week Wednesday. They will also have a full practice Thursday before their typical quick Friday practice and Saturday walk-through, which means there is still a chance Mathieu will be able to join the Chiefs before the Browns visit Arrowhead Stadium on Sunday.
The Chiefs/Browns game can be heard on 94.5 the X, with the pregame at 2:00 and the kick off at 3:25.
