The Dallas Cowboys have been named as the most valuable NFL franchise for the seventh consecutive year in the Forbes list.
The Cowboys were valued at $2.3bn, around half-a-million dollars more than second-placed New England Patriots, who are worth $1.8bn.
Jerry Jones's side have not won the Super Bowl since 1996 but were given a big financial boost during the off-season due to AT&T's $400m deal for the naming rights to their stadium.
The Washington Redskins ($1.7bn), New York Giants ($1.55bn) and Houston Texans ($1.45bn) make up the top five, while the Oakland Raiders were named as the least valuable franchise, worth $825m.
None of the franchise decreased in value, with Kansas City Chiefs the only one not to increase as it stayed at $1bn.
The Baltimore Ravens, meanwhile, moved into the top 10 courtesy of their Super Bowl success.
The average value for an NFL franchise was $1.17bn, putting it above the average values of the top 20 football, baseball and basketball teams.
