Sunday's postponed NFL game between the Tennessee Titans and Pittsburgh Steelers will now be played later in the season.
The week four game was postponed after a Covid-19 outbreak among Titans players and staff, with the NFL hoping to reschedule the match for Monday or Tuesday.
However, another Titans' player has now tested positive for coronavirus.
The NFL says an announcement of the new game date will be made shortly.
Titans players DaQuan Jones, Beau Brinkley and Tommy Hudson were all put on the reserve/Covid-19 list on Tuesday.
"The Titans facility will remain closed and the team will continue to have no in-person activities until further notice," said an NFL statement.
The Titans played the Minnesota Vikings in Minneapolis last Sunday.
The Vikings' facility was also closed on Tuesday and Wednesday and it is unclear whether their scheduled game with the Houston Texans will take place on Sunday.
