Incognito, who said he found acceptance with the Las Vegas Raiders after a star-crossed and controversy-filled career, announced his retirement on Friday.

Incognito played in just 14 games with the Raiders due to injuries. He last appeared in the second week of the season.

Incognito said in a letter posted on the Raiders' website that he felt right at home with the team. They allowed me to play because they trusted me. I played my cards close to the vest to repay them.

I am a big fan of the Raiders organization. Mark is the world to me. I'm retiring a Raiders after 15 years.

Incognito was drafted in the third round. The Miami Dolphins and Buffalo Bills were both teams that the Louis Rams were a part of.

He went to three straight Pro Bowls after signing with the Bills, but then retired after the season because his organs were failing.

After an incident with his grandmother, he pleaded guilty to two counts of disorderly conduct.

Mike Mayock was the general manager of the Raiders when they signed him in the spring of 2019.

Even though he had trouble with the Raiders, Incognito stayed out of trouble. He played 12 games that first year and was given a two-game suspension for the funeral home incident.

Incognito suffered a season-ending injury in Week 2 of the 2020 season, and then suffered a calf injury in a joint practice last August. Several O-linemen attended Incognito's retirement media conference as he was seen as a positive influence on the Raiders' offensive line.

Incognito advocated for mental health.

Incognito has dealt with injuries the last two years. I knew it was time to hang them up. Some in my circle might not believe me, but I'm prepared. There isn't a turn back.

I returned. My goal was set by me. I made it happen.
