Lester Martinez vs Luka Plantic: How to Watch, Start Time, Full Card and Stream on ProBox TV
Lester Martinez vs Luka Plantic headlines the biggest ProBox TV card to date on Saturday, August 29, at the Galen Center in Los Angeles. Martinez, the WBC interim super middleweight champion, puts his unbeaten record and title on the line over 12 rounds against the undefeated Plantic, with a shot at the full WBC 168-pound title waiting for the winner.
Here's everything you need to know: start time, how to stream, the full fight card, and why this one matters.
How to Watch Lester Martinez vs Luka Plantic
The entire show streams on ProBox TV via YouTube. Sign up at proboxtv.com.
Saturday marks a new era for ProBox. After four years of free fights, the Championship Series now costs $5 per month, with no long-term commitment and the ability to cancel anytime. The earlier Future Stars portion of the card remains free.
That first $5 also covers ProBox's next show on September 11, when junior middleweight contenders Abass Baraou and Giovani Santillan meet.
What's at Stake in Martinez vs Plantic
More than an interim belt is on the line. The winner is firmly positioned for a shot at the full WBC super middleweight championship, currently held by Christian Mbilli, who faces Canelo Alvarez on October 31.
Martinez has unfinished business with Mbilli after their thrilling draw last year, but the bigger prize is obvious: a win over Plantic could put him within touching distance of a Canelo Alvarez blockbuster.
Plantic, who beat Mbilli as an amateur, is chasing the same path.
