According to several sports analysts, American football is one of the toughest sports in the world. So, when Las Vegas Raiders linebacker, Blake Martinez, found himself a way out of the NFL, he took it.

At just 28, Martinez is supposed to be in the prime of his career. However, after apparently making enough money selling Pokemon cards, Martinez decided to call it quits right in the middle of the season after seven years in the NFL.

Martinez was drafted by the Green Bay Packers in 2016, where he spent four years before he joined the New York Giants in 2020. After suffering a torn ACL a year into his tenure with the Giants, the team released him and he subsequently signed with his latest team, the Las Vegas Raiders.

For all intents and purposes, Martinez's season was going rather well as he had racked up 11 tackles before his surprise retirement. However, after recently selling a very rare Pokemon card for nearly $700,000, Martinez is now ready to pursue his less injury prone but an equally-lucrative passion.
