<h2>Luis Alberto Lopez vs. Joet Gonzalez undercard</h2>
<h3><a href="https://www.sportingnews.com/uk/boxing/boxer-profile/2-contestant-87241… Zayas</a> vs. <a href="https://www.sportingnews.com/uk/boxing/boxer-profile/2-contestant-79332…; target="_blank">Roberto Valenzuela Jr.</a></h3>
<ul>
<li><b>Division/Weight</b>: Super welterweight</li>
<li><b>Zayas record</b>: 16-0</li>
<li><strong>Valanzuela Jr</strong><b><strong> </strong>record</b>: 21-4</li>
<li><b>Belts at stake</b>: N/A</li>
</ul>
<p>Zayas, who signed for Top Rank as a 16-year-old and has been called "Puerto Rico’s next superstar" by promotion boss Bob Arum, faces a step up in experience against Valenzuela.</p>
<p>Now 20, Zayas has good reason to call Valenzuela a "Mexican warrior" because of his record of 20 knockouts from 21 wins. The 24-year-old has lost four times.</p>

<h3><a href="https://www.sportingnews.com/uk/boxing/boxer-profile/2-contestant-81916…; target="_blank">Omar Aguilar</a> vs. <a href="https://www.sportingnews.com/uk/boxing/boxer-profile/2-contestant-75146…; target="_blank">Julio Luna</a></h3>
<ul>
<li><b>Division/Weight</b>: Welterweight</li>
<li><b>Aguilar record</b>: 25-1</li>
<li><b>Luna record</b>: 20-1-2</li>
<li><b>Belts at stake</b>: N/A</li>
</ul>
<p>An all-Mexican contest pits two fighters who are looking to earn successive wins a year on from suffering career setbacks</p>
<p>Luna lost by decision to Giovani Santillan in August 2022 – the same month Aguilar lost his unbeaten record to Lindolfo Delgado. Luna then beat Hassam Valenzuela in three rounds in March, before Aguilar defeated Cristian Sonora Soltero in two in May.</p>

<li><b>Ortiz record</b>: 16-1-1</li>
<li><b>Moran record</b>: 13-1</li>

</ul>
<p>Known as 'The Technician', Ortiz returns for the first time since taking Vasiliy Lomachenko to the scorecards in a unanimous decision defeat last October.</p>
<p>His opponent in a 10-rounder is a 30-year-old Mexican with 20 knockouts to his name who has only been stopped once.</p>

<h3><a href="https://www.sportingnews.com/uk/boxing/boxer-profile/2-contestant-77297…; target="_blank">Robson Conceicao</a> vs. <a href="https://www.sportingnews.com/uk/boxing/boxer-profile/2-contestant-80071…; target="_blank">Humberto Galindo</a></h3>

<li><b>Conceicao record</b>: 17-2</li>

</ul>
<p>Last seen taking part in a no-contest against Nicolas Polanco in June, Rio Olympics gold medalist Conceicao is back in an eight-rounder.</p>
<p>Mexico-born American Galindo is seeking to end a run of two defeats against the two-time title challenger and has 11 knockouts from his 14 wins.</p>

<h3><a href="https://www.sportingnews.com/uk/boxing/boxer-profile/2-contestant-76842…; target="_blank">Ruben Villa</a> vs. <a href="https://www.sportingnews.com/uk/boxing/boxer-profile/2-contestant-75056…; target="_blank">Brandon Valdes</a></h3>

<li><b>Villa record</b>: 20-1</li>
<li><b>Valdes record</b>: 15-3</li>
<li><b>Belts at stake</b>: N/A</li>
</ul>
<p>American Villa lost by unanimous decision when he challenged Emanuel Navarrete for the WBO featherweight in 2020 but has won twice by knockout since then, most recently beating Maickol Lopez Villagrana in five rounds in May.</p>
<p>All of Colombian Valdes' three defeats have come in his past five fights. The 25-year-old beat Angel Antonio Contreras in April and takes on Villa over eight rounds.</p>
<hr />
<h3><a href="https://www.sportingnews.com/uk/boxing/boxer-profile/2-contestant-85681…; target="_blank">Tiger Johnson</a> vs. <a href="https://www.sportingnews.com/uk/boxing/boxer-profile/2-contestant-79060…; target="_blank">Ricardo Quiroz</a></h3>

<li><b>Johnson record</b>: 9-0</li>
<li><b>Quiroz record</b>: 13-2</li>
<li><b>Belts at stake</b>: N/A</li>

<p>Unbeaten Olympian Johnson, who beat Jonathan Montrel conclusively on points in July in his third fight of 2023, takes part in an eight-rounder.</p>
