Best thing you could do is overseed it now with a nurse crop of Rye Grain (NOT GRASS) , or wheat ! This will protect the new clover, and also help control weeds, and grass next spring/summer.
You also might come back around Febuary and frost seed in some clover, to fill in some gaps, and get your clover seed/plant count up going into the spring.
Once the Rye or wheat gets around 8 to 10 inches high come spring, go in a mow the plot back to around 6 inches.
The Rye/Wheat will eventually brown and die off, leaving a weed/grass free clover plot
