CARSON, Calif. - Oscar De La Hoya and Golden Boy Promotions hosted the final press conference earlier today for this Saturday's potentially explosive world championship tripleheader live on SHOWTIME® (9 p.m. ET/6 p.m. PT) from StubHub Center in Carson, Calif.

In what should be a thrilling, non-stop action three-fight telecast, IBF Welterweight World Champion "ShowTime" Shawn Porter (24-0-1, 15 KOs), of Cleveland, Ohio, will defend against fellow unbeaten Kell Brook 32-0, 22 KOs), of Sheffield, England.

"Let's let him [Brook] know what time it is," Porter yelled as he stepped up to the mic. Some in the audience responded,"It's "Showtime!"

After repeating this, Porter then stared down at a still-seated Brook and said. "I think you know what time it is. Saturday night I'm going to make sure you know what time it is." Porter said thank you and then sat down.

Here's what Brook said during Thursday's press conference at StubHub Center:

"This has been a long time coming, but I've finally arrived on the top stage now. It's every fighter's dream to win a world title, and it's all I've been thinking about through all the training and waiting," Brook said.

"I know Shawn Porter is a very tough customer and a very worthy champion. But this is my time. I'm so ready mentally, and physically, I've got my family here. I'm just in the best place of my life. I'm very confident, totally prepared and Saturday could not come quick enough for me.''
