What is the right decision?

If a fighter gets kneed to the groin and cannot continue after 5 mins of rest? does the offender get disqualified for this?

Does it matter what round it is in?

If a fighter gets poked in the eye in the 1st round and going into the 2nd round he cannot continue due to the poke in the eye from the 1st round? what would be the right outcome? Do scorecards come into play?

Anyone who can shed some light on this?
