Optional Plan: Get Aggressive
If you're dealing with a buck that's not likely to make it to a food source before dark, make him think he's missing the action. March toward his bedding area in early afternoon and set a ground blind on the downwind side of the best trail leading from the bedding area. Make three mock scrapes and douse them with estrous scent. Back into your hide and give the woods time to settle down. An hour before dusk, start hitting the grunt call, building in volume and intensity. Then stage a mock battle with your antlers, keeping the volume moderate (after all, you're tight to his bed). If he doesn't come immediately to your calls, you've given him motivation to get on his feet early, and a direction to go when he does so.
