Clay Guida, a ufc hall of famer, is reportedly competing in the us open wrestling championships, while also being involved in the raf, which gives retired mma fighters a second act. Guida has had a 22-year mma career and has been competing at 44 years old, with some indications that he may be transitioning away from mma. The nature and current status of his mma career are unclear, with some reports suggesting he has "kind of hung up the gloves".
