Watching MMA for the last like 7 years has both desensitized me to seeing guys get knocked out and made me realize the consequences of it.
People talking about making sure he's not dead from that? Ok, settle down. I've seen a guy run across the cage, flying knee a guy in the face, and then punch him multiple times when he was clearly unconscious on the ground. That guy (eventually) sat up and walked out of the cage.
On the other side, "I hope he's OK", he's definitely not OK. Getting knocked out is not OK. Obviously a fighter is different because they are going to get hit in the head again even during training, but a fighter would be out for minimum 3 months after getting knocked out. Most should probably take more like 6+ months. I would be surprised if they let Ludvig play again before 2024.
