Brock Lesnar is done. The 10-time WWE world champion and former UFC heavyweight titleholder announced his retirement from combat sports after his match at SummerSlam, signaling the end of a career that spanned both wrestling's biggest stage and mixed martial arts at the highest level.

Lesnar's departure marks the end of an era for WWE. He's been one of the company's most bankable attractions for years, a draw who could main event WrestleMania or premium live events on name recognition alone. His ability to move between WWE and UFC made him a rare crossover star, someone who could headline pay-per-views in two completely different sports.

The timing matters. Lesnar has been selective with his appearances in recent years, working a limited schedule. SummerSlam served as his final statement. No drawn-out farewell tour. No extended goodbye. Just a match and a walk.

His 10 world titles rank among the most in company history. He won gold across multiple eras and against different generations of wrestlers. Whether he steps away completely or leaves the door cracked open for future returns remains to be seen, but his words were clear. That's it.
