Kaepernick has maintained he didn't use the language and will appeal the fine.
The language allegedly occurred after Kaepernick threw an interception in the fourth quarter of the 49ers loss to the Bears on Sunday. Kaepernick pointed out that Chicago defensive lineman Lamarr Houston, who the words were allegedly said to, has told reporters that he didn't hear them.
“The player that I supposedly said something to has been quoted saying that I didn't say anything,” Kaepernick said. “And I don't know him. So it's not like he would have a reason to just randomly stick up for me.”
Kaepernick received a letter from the NFL about the fine, which he said did not specify what language was used.
The side judge who threw the flag recently told CSN Bay Area that Kaepernick “knows what he said.”
