Zhilei Zhang finishes Deontay Wilder in brutal 5th-round TKO

Zhilei Zhang scored the biggest win of his career Saturday in Riyadh, Saudi Arabia, and might have effectively ended former heavyweight champion Deontay Wilder's run in the process.

China's Zhang, 41, connected with a perfectly timed counter right hook that spun Wilder in a daze. With Wilder defenseless, Zhang (27-2-1, 21 KOs) sprinted in and smashed him with another right hand that planted the American hard on the canvas.
