Days out from their boxing showdown, Jake Paul and Mike Tyson appeared in the ring for their open workouts.

27-year-old "EL Gallo," a YouTuber-turned-pugilist, and 58-year-old "Iron Mike," a former undisputed world heavyweight champion, are set to do battle as the headline act of the very first combat sports event to be streamed live on Netflix.

The event takes place at the AT&T Stadium in Arlington, Texas this coming Friday. It was originally scheduled for July but had to be postponed due to a medical issue on the side of Tyson.

Four months later, the pair have renewed hostilities ahead of their collision atop the Nov. 15 card, which also features a highly awaited championship rematch between boxing stars Katie Taylor and Amanda Serrano.

All four featured at Tuesday night's open workouts, the full replay and highlights from which you can see below.
