During yesterday's WWE Crown Jewel event Brock Lesnar defeated Cain Velasquez and made the former MMA star tap out to the Kimura Lock to retain the WWE Championship in a little over 2 minutes.

Wrestling Observer is reporting that the match was kept short because Cain’s knee not in a good way and he requires surgery soon.

The original plan was for a short match with some big moves, but Valasquez just couldn't do it and they decided on the quick finish.
