Per ESPN's Adam Schefter, the league announced Incognito is suspended for the first two games of the 2019 season.
According to NFL Network's Tom Pelissero, the suspension stems from Incognito's arrest at a funeral home in Scottsdale, Arizona, in August 2018.
Per A.J. Perez of USA Today, Scottsdale police arrested Incognito after he threatened to shoot the staff at a mortuary as arrangements were being made for his father's funeral.
In April, TMZ reported Incognito pleaded guilty to a misdemeanor count of disorderly conduct in the funeral-home case.
Incognito also pleaded guilty to two misdemeanor charges of criminal damage and disorderly conduct stemming from a separate August 2018 incident in which he punched a hole in the wall and ripped a security system control box off the wall at his grandmother's home because he blamed her for his father's death.
The Raiders signed Incognito to a one-year deal in May. The 36-year-old last appeared in an NFL game with the Buffalo Bills in their 10-3 loss in the AFC Wild Card Game to the Jacksonville Jaguars on Jan. 7, 2018.
