Richie Incognito is back in the NFL. The troubled offensive lineman officially signed a one-year contract with the Oakland Raiders on Tuesday after sitting out the duration of the 2018 season.

Incognito initially stated his intention to retire from the NFL before the 2018 season. He later said that he was looking forward to reporting to the Buffalo Bills' offseason program, but the team cut him instead despite some major holes on the offensive line. Incognito then went on to publicly and profanely criticize Minnesota Vikings coach Mike Zimmer after the team made it clear it wasn't interested in signing him as a free agent.

Far more concerning were subsequent run-ins with law enforcement that, unfortunately, called Incognito's mental health into question. Last May, he was detained for an involuntary mental evaluation after he purportedly threw dumb bells and tennis balls at another patron of a gym in Boca Raton, FL. While in custody, Incognito reportedly told police that he was an NSA agent who was being tracked by government agents. Three months later, he allegedly threatened to “shoot people” at a funeral home in Scottsdale, AZ following the death of his father, a threat for which he ultimately pled guilty to disorderly conduct, avoiding jail time.

Incognito first earned national infamy as a member of the Miami Dolphins in 2013. After tackle Jonathan Martin abruptly left the team just one year removed from being a first-round pick, reports surfaced that Incognito's incessant bullying, which included the use of racial slurs, is what prompted the Stanford product to be unwilling to continue playing for the Dolphins. Incognito was suspended for “conduct detrimental to the team,” missing the last two months of the 2013 season.
