Alex Perez's fight at UFC Macau on May 30, 2024, took a distressing turn when he suffered a severe low blow from his opponent, Sumudaerji. Perez, who had previously knocked out Charles Johnson at UFC 324, was looking to secure his first winning streak since 2020. He started strong, winning the first round on two judges' scorecards. However, the fight ended abruptly in the second round when the low blow inflicted significant damage, causing Perez to retch into a bucket inside the Octagon. This incident led to the fight being ruled a No Contest. Following the bout, Perez was transported to a hospital for a precautionary testicular ultrasound, although no results have been disclosed yet. The unfortunate turn of events not only halted Perez's aspirations for consecutive victories but also interrupted Sumudaerji's three-fight winning streak, as his inability to control his strikes cost him a chance at extending his success in the UFC.
