The week 16 match between the Chicago Bears and the Philadelphia Eagles has been moved to a night-time slot by the NFL.
The match, initially scheduled for 6pm GMT on Sunday, December 22, will now take place at 1.30am GMT on Monday, December 23, giving it a primetime slot in America.
The New England Patriots' match against reigning Super Bowl champions the Baltimore Ravens was originally due to be in that spot, but has now been moved to 9.25pm GMT on the Sunday.
The Bears-Eagles match could be a potentially crucial one in two divisions, with both sides chasing a place in the playoffs.
Chicago are currently level with the Detroit Lions at the top of the NFC North, while Philadelphia lead the way in the NFC East, one win ahead of the Dallas Cowboys.
The match will be the penultimate encounter of the regular season, with the Bears and the Eagles ending their campaigns against the Green Bay Packers and the Cowboys respectively a week later.
