LOS ANGELES (AP) — Southern California senior cornerback Josh Shaw injured both ankles after leaping from a second-story balcony to save his 7-year-old nephew, Carter, from drowning in a pool.

Shaw was named a team captain on Saturday and later that night was attending a family function at a cousin’s apartment in his hometown of Palmdale when he saw his nephew, who can’t swim, struggling in the pool.

With no one around, Shaw told USC’s website that he instinctively jumped from the balcony onto the concrete below and crawled to the pool, where he pulled Carter to safety. Unable to step out of the pool because of the pain in his ankles, Shaw lifted himself up the ladder with his upper body.

Shaw was taken to the hospital where he was diagnosed with two ankle sprains. He said Carter was traumatized, but physically in good shape.
