Yesterday I knacked a big chunk of my lawn.

I was replacing the lower panel in my back door and laid the door on the
lawn to work on it. Unfortunately the top half is glass and the rays of the
sun have scorched a large rectangle of grass.

The grass isn't just a bit yellow, as it tends to go in hot sun, but totally
fried to a grey brown colour.

Do you think it will eventually come back with lots of water or will I have
to re-seed or re-turf?
