injured creature in magic blocking trample creature rules

[Tilo]

if i cast a lightning bolt on a 4/4 creature

then in the same turn i attack with a 7/7 creature with trample and it is blocked by hurt creature

how much damage does trample deal, 3 or 6?

Up to 6. When assigning damage, trample takes into account any damage previously dealt to the creature that turn.
