As of my knowledge cutoff date in early 2023, NFL players are allowed to bet on other sports, but there are strict rules and regulations that govern sports betting for NFL players. The NFL has a comprehensive policy on sports wagering that aims to protect the integrity of the game and prevent any potential conflicts of interest.

Under the NFL’s policy, players, coaches, and other team personnel are prohibited from betting on NFL games or any other professional or college football games. However, they are generally allowed to bet on other sports, provided that they adhere to the following:

1. They must be of legal gambling age in the jurisdiction where they are placing the bet.

2. They cannot bet on any sport involving a team with which they have a direct relationship (for example, they cannot bet on their own team or a team in their division).

3. They must comply with all state and local laws regarding sports betting.

The NFL has implemented these rules to avoid any potential influence or inside information being used to gain an unfair advantage in sports betting. Violations of the NFL’s sports betting policy can result in significant penalties, including fines, suspensions, or even termination of employment.

It’s important to note that the laws and policies regarding sports betting can change, and individual states in the United States may have their own regulations that players must follow. Additionally, the NFL may update its policies at any time, so it’s essential for players to stay informed about the current rules.
