Let in the clowns

An amateur bull rider insists on riding a more aggressive bull before he is truly ready for the challenge. He mounts the bull in the chute and is thrown within moments of the gate opening, after which the bull turns on the rider to try and gore him. A rodeo clown stationed near the chute immediately rushes over to “pull” the bull away by waving his cape. The bull immediately swirls and instead of attacking the rider, charges the clown and gores him. Fortunately, since this is a trainer bull, the tips of the horns had been shorn flat and the clown, although suffering a severe body blow, is not gored. That evening the teenage rider goes out with his friends and relates his story of how he skipped injury fighting off a huge bull. The clown, meanwhile, goes home after gathering his wits about him, and is examined by a clinician to ensure there are no motor deficits in his right lower limb. However, when undressing to shower, the clown notices that the area just anterior to the medial malleolus of his right foot feels numb. In fact, he asks his wife to prod the area with a sharpened object (while he covers his eyes) and notices that there is no sensation. Based on these findings, what is the most likely site where the bull “gored” the clown?
