The approval process from the NFL for Tom Brady's proposed deal to purchase a minority ownership stake in the Las Vegas Raiders has stalled as there are concerns about the discounted price. 

The deal would be unlikely to be ratified at the proposed price, which is up to a 70 percent discount. Brady is purchasing a stake in the Raiders between five and 10 percent.

There is strong sentiment within the finance committee that the deal “can’t happen at that price” and will not be approved without modifications.

The Raiders are worth an estimated $6.2 billion, according to Forbes’s NFL team valuations released in August. 

Forbes estimated in February that Brady earned more than $530 million from playing contracts and off-field business ventures during his 23 NFL seasons.
