Brock Lesnar emerged victorious from last night's WWE SummerSlam main event after victory over Randy Orton and finished his opponent with some vicious elbows to the head.

The injuries sustained were quite real and required ten stitches as a result. It would appear that Lesnar is still very much in the UFC mindset after some rather routine ground and pound escalated and drew blood from Orton's head, opening a nasty gash in his crown.

Lesnar featured in the UFC's landmark event, UFC 200, in July when he fought Mark Hunt, but was later found to have used a banned substance. His future with the promotion remains in doubt as a result.

Orton had recently made reference to the fact that Lesnar had been caught doping in the build up to the fight.
