Leicester City moved eight points clear at the top of the table with an emphatic 4-0 victory over Swansea City on Sunday.
Many pundits have questioned Leicester's ability to continue their surge towards the Premier League crown with such a small squad, but King explained how Sunday's result is evidence of their strength in depth.
"It is massive for him and for us," he said. "If we hadn't won, everyone would have said we missed Vardy. There is no doubt about it, Vardy was a big loss for us, because the way he has played this season has been outstanding, but we showed the strength in depth we have today."
The former Fleetwood Town man has indeed been a key figure in the Foxes' incredible rise to the top, scoring 22 goals in 34 league appearances. As good as Vardy has been, however, it is Leicester's team ethic and unity that has seen them establish an eight-point lead over second-placed Tottenham Hotspur.
In Vardy's absence, Claudio Ranieri called upon his reliable stand-in Leonardo Ulloa, and his performance proved the doubters wrong and showed that Leicester can still win without their star striker.
King went on to say how happy he was for Ulloa.
"Everyone is buzzing for Leo, Vardy included," he said.
If Leicester can pick up five points from their remaining three games they will be crowned Premier League champions, in what would be arguably the greatest ever feat achieved in English football.
