Domestic abuse is something that is not taken lightly by most organizations, including the NFL.

On Monday, celebrity news website TMZ released a video showing NFL player Ray Rice throwing a punch at his wife, Janay Palmer. The video was submitted to the NFL by an unnamed law enforcement agent.

NFL spokesperson Brian McCarthy claims that they had absolutely "no knowledge" about the tape upon its leaking.

"We have no knowledge of this," said McCarthy, claiming the league was not aware that such a video exited until it was leaked by TMZ.

"We are not aware of anyone in our office who possessed or saw the video before it was made public on Monday," McCarthy told the Associated Press.

"We will look into it," the league spokesperson added.

However, the Associated Press suggests otherwise, reporting that the league knew about the tape and claiming that there is a 12-second voicemail recorded on April 9^th.

"You're right, it's terrible," a woman's voice affirmed on the alleged tape.

NFL commissioner Roger Goodell sent a statement to all 32 NFL club owners and executives, saying that the league asked law enforcement about Rice's video, but not the Atlantic City casino.

"[On] multiple occasions, we asked the proper law enforcement authorities to share with us all relevant information, including any video of the incident," Goodell said in the statement.

"[We] did not ask the Atlantic City casino directly for the video," the commissioner added.

In a recent statement, NFL confirmed that Robert S. Mueller III, FBI director, will conduct a probe into how the league decided to "handle" the video, and how the league is claiming that they had no prior knowledge of it.
