Cops said Incognito appeared to be in an "altered paranoid state" during the incident. He was placed on an involuntary psychiatric hold. He was released a few days later.

Incognito had announced he had retired from pro football after the 2017 season -- but told TMZ Sports he was open to signing with a team in 2018 if the money was right.

We've reached out to Richie and his attorney for comment -- so far, no word back.

Incognito was a helluva player during his 13 seasons in the NFL -- making the Pro Bowl 4 times and reportedly earning more than $25 million dollars in contract money.

Incognito was infamously linked to the Miami Dolphins bullying scandal back in 2013 -- when he was suspended for misconduct for hazing teammate Jonathan Martin.

Years later, Martin threatened Incognito on social media -- and was apprehended by police a short time later. Cops found guns and knives on Martin at the time of his arrest.

Incognito told TMZ Sports he had no hard feelings for Martin and was praying for him.
