The Cleveland Browns have placed quarterback Baker Mayfield on the reserve/COVID-19 list.

Mayfield being added to the list means he has either contracted coronavirus or has come into contact with a person who has tested positive, league rules prevent the Browns from saying which category he falls into.

The Browns also confirmed that a staff member had tested positive and that close contacts had immediately gone into self-isolation.

A statement read: "The Cleveland Browns were informed Saturday morning that a staff member tested positive for COVID-19.

"Contact tracing was conducted and close contacts were immediately self-isolated.

"When the team returns to work following the bye on Monday, it will follow the NFL-NFLPA intensive protocol.

"We will continue to work closely with the league and medical experts on the appropriate next steps with the health and safety of our players, coaches and staff members remaining our highest priority."

Cleveland face the Houston Texans when they return from their Week 9 bye. The Browns are reportedly hopeful running back Nick Chubb will be able to return from an MCL sprain to feature in that game.

Another quarterback to have been recently placed on the reserve/COVID-19 list, Matthew Stafford of the Detroit Lions, is set to play in Week 9 against the Minnesota Vikings.

He was activated off the list on Saturday and returned a negative test on Sunday as the Lions look to move to 4-4.
