Richie Incognito has announced his retirement.

Incognito, 39, signed with the Las Vegas Raiders in 2019 and played in just 14 games with them because of injuries. He last appeared in Week 2 of the 2020 season.

"It felt like home the minute I got here," Incognito said in letter posted on the Raiders' website, "and I'd gotten this 'bad boy' reputation, but it just fit with the Raiders. They trusted who I was, and they let me play. And I played my ass off just to repay them for the opportunity.

"I love the Raiders organization, and Mr. [Mark] Davis means the world to me. It's why after four teams and 15 years, I'm retiring a Raider."

Incognito was a third-round draft pick of the then-St. Louis Rams in 2005 and also spent time with the Miami Dolphins and Buffalo Bills.
