If Burnley and/or Leeds lose their next fixture and we win tonight, I believe we would only need one point from our remaining three fixtures to be safe..
Unless I've totally miscalculated.
If we win tonight we go four points clear of those two teams.
If they both lose their next game they can still mathematically get another six points.
So no, sadly we will still need another three points if we win tonight.
(though two would do it as Leeds GD is way worse than ours).
