Jacksonville Jaguars defensive end Yannick Ngakoue says Buffalo Bills guard Richie Incognito used “weak racist slurs” during their playoff game on Sunday.

Ngakoue voiced his complaint on Twitter, calling out Incognito by his No64 jersey.

Ngakoue wrote: “Great win today! And 64, you goin have to come harder than some weak racist slurs. I’m proud of my African heritage, as are 70% of the other Black players in this league. #Iaintjonathanmartin!”

YANNICK NGAKOUE! (@YannGetSacks91) Great win to day! And 64, you goin have to come harder than some weak racist slurs. I’m proud of my African heritage, as are 70% of the other Black players in this league. #Iaintjonathanmartin!

The hashtag referenced an NFL investigation that found Incognito and two Miami Dolphins team-mates engaged in persistent harassment directed at fellow offensive lineman Jonathan Martin, who left the team in the middle of the 2013 season. Incognito was subsequently suspended for the final eight games and sat out the 2014 season before joining the Bills.

During the 2013 investigation, Incognito admitted directing the N-word at Martin in a voicemail but denied he was racist.

“I’m not a racist. To judge me by that one word is wrong,” he told Fox Sports. “In no way, shape or form is it acceptable for me to use that word, even if it’s friend to friend. It’s thrown around a lot. It’s a word I’ve heard [Martin] use a lot – not saying it’s right for when I did it in the voicemail, but there are a lot of colorful words thrown around in the locker room that we don’t use in everyday life. The fact of the matter remains, though, that the voicemail was left on a private voicemail for my friend, and it was a joke.”

On Monday, Incognito’s team-mate Dion Dawkins came to his fellow lineman’s defence. “[I] was next to my guy the entire game and the entire season and believe me, if he was saying some racist stuff I would have been the first to let him know that was out of line,” wrote Dawkins on Twitter.

Dion Dawkins (@DDawkins66) Just for the world to know, everyone always tryna put some bad thing on @68INCOGNITO i was next to my guy the entire game and the entire season and believe me, if he was saying some racist stuff I would have been the first to let him know that was out of line. Cut The BS

The Jaguars beat the Bills 10-3 on Sunday, ending Buffalo’s season. No other Jacksonville players mentioned racial slurs or Incognito in the locker room after the game.
