Terrance McKinney had a blockbuster debut at UFC 263 on Saturday.
The he appeared to injure himself.
The 26-year-old lightweight took on Matt Frevola for his first appearance in the Octagon during the UFC 263 prelims. The fight was over almost as soon as it started.
Immediately after the pair met in the middle to touch gloves, McKinney floored Frevola with a vicious right-left combo. He then jumped on Frevola to ensure that the job was done, but it didn't take the referee long to call the fight. The wrestling specialist who previously said he was joining UFC "to knock people out" had followed through on his vow in dramatic fashion.
