Sanji wasn't knocked out by Imu's attack
As we can see PLAINLY, after the attack Sanji is laying on the ground injured talking to Qillingham.
After Qillingham leaves by jumping off Sanji, we see him get blown away by Loki and Imu's "clash" over to Lilith and Bonney.
With Lilith and Bonney he almost immediately gets back up and starts regening while racing back to fight.
Unless we are saying bro got knocked out for such a short time before Qillingham came which would be crazy because that first "clash" was one of the FIRST things to happen in 1181, then Sanji was NEVER knocked out.
He was just laying on the ground injured like Zoro was.
