No one gets cut for landing extra punches after a guy is knocked out. Raja was just going until the ref stopped him, that's on the referee.

In fact, follow up shots on unconscious opponents are some of the most viral and beloved moments.

As long as you stop when the ref intervenes and not a second before, you'll be loved by everyone for the excessive violence.
