The reason why Brock Lesnar vs. John Cena isn't on WWE Clash in ParisBrock Lesnar returned to WWE at the end of SummerSlam and attacked John Cena.

While still unannounced, the show is set to go head-to-head with AEW All Out.WrestleTalk @WrestleTalk_TVLINKWWE is reportedly planning Brock Lesnar vs John Cena as the main event of the September 20 PLE on the same day as AEW All Out:"It can change, but the main event for this show is Brock Lesnar and John Cena. So it's a big one. Which is why Brock's not in Paris, is because of this."They wanted him for this show, not the Paris show, and that's where Logan Paul got the gig."(Dave Meltzer on WOR)These plans are why The Beast Incarnate hasn't appeared since SummerSlam, allowing Logan Paul to face Cena at Clash in Paris.#2.

Concerning update on NaomiNaomi was supposed to defend her Women's World Championship against IYO SKY on RAW this week. However, WWE abruptly announced she wasn't medically cleared to compete hours before the show, causing the match to be canceled.Speaking on Wrestling Observer Live, industry insider Bryan Alvarez has suggested he heard rumors from WWE that would suggest Naomi will be out of action for a long time:"There is definitely a rumor going around in WWE about what’s going on with Naomi, and like it’s being talked about by people there, and if it is, in fact, what’s going on, she is going to be out for a long, long time. Okay, I’ll just say that for now. My presumption is that, you know, people will find out probably fairly soon, but I think that that it would be a while. If this is the case," he said.While the exact rumor was not revealed, it has sparked concern across the wrestling world. Sportskeeda Wrestling sends its best wishes to Naomi if she is injured and set to be out for a long time.
