CNN.com's Jill Martin reported the news Monday, a day after Ngakoue took to Twitter to accuse Incognito of directing a slur at him during the game.
Ngakoue wrote: "Great win today!"
Ngakoue said on Twitter Sunday night that a Bills player wearing No. 64 was "goin [g to] have 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. "I don't know anything about it".
"I have no comment on that", Dareus said.More news: GoPro's drone efforts have failed

Ngakoue said he didn't recall the N-word being used and was unsure if any of teammates heard the comments, but he was "sure" some Bills players did. Like I said before, we had a great team win yesterday.
As a member of the Dolphins, Incognito was infamously suspended for the final eight games of the 2013 season for "a pattern of harassment" which included racial slurs, homophobic taunts and other forms of harassment directed at then-teammate Jonathan Martin.
Ngakoue said he had never heard the alleged term Incognito used in all of his years of playing football. I understand trying to give yourself an advantage, and you see somebody trying to egg them on to try to get a penalty, I understand that. "And if he did, (you) best believe I would've been one of the first people to basically check him on it because there's races".
Incognito, 34, signed with the Bills before the 2015 season and has made the Pro Bowl in each of his three years with Buffalo.
"I didn't hear anything but I know how Yan is", Jones said. The accusation turned into a lengthy investigation, which uncovered a racially charged voicemail Incognito left for Martin.
