Just when two of the big three American sports leagues – the NBA and MLB – have warmed up to the idea of US sports betting in the future, money-making enterprise NFL is having cold feet about jumping on the bandwagon.

Yahoo! Finance reported that the NFL is not rushing to join calls for the legalization of sports betting in the US, as it expresses their apprehension on how legalized gambling would affect the football games itself.

The NFL, known for being tight-lipped on all issues, gave a hint of its position on legalized sports betting through its senior labor relations counsel Brook Gardiner, who spoke at the 30th annual National Conference on Problem Gambling, in Tarrytown, New York.

Gardiner expressed fear that the integrity of the sport will be compromised should NFL throws its support for the legalization of sports betting.
