Watch: Mayweather says he hasn't cashed Pacquiao, McGregor fight checks

Floyd Mayweather hasn't touched a penny of his earnings from the Manny Pacquiao and Conor McGregor fights.

The retired boxer, who reportedly received around $300 million for each bout, told TMZ Sports on Thursday night that he has yet to cash either check and plans to post photos of them on social media to prove it.

He also addressed reports that he's facing a $22-million tax lien from the IRS, saying, "I still own all my houses, still own all my cars."
