"We're delighted to be in that hat and I'm sure Grimsby will be just as much as we are. We could have lost it and we could have won it," said Laws.
"It ended up being exactly like we thought it would pan out. It was very hectic and devoid of quality.
"There wasn't a lot of time on the ball and every ball was contested.
"We might have been favourites but there's not much between the two teams. There was a lot at stake for both clubs, but we've both got another bite of the cherry."
Mariners boss Paul Hurst said: "I enjoyed it and I'm sure the fans did. That's as good a 0-0 as you're going to get.
"There was a fantastic atmosphere but we didn't freeze, we played the sort of football I think we're capable of and credit to the players for that.
"I thought we had the better of large parts of the game and probably should have won it. Their keeper made some good saves and we wasted a couple of chances.
"Scunthorpe hung in there and had a good spell at the end of the game where they could have nicked it."
