BY DAVE HOGG, The Associated PressMOUNT PLEASANT, Mich. — Mason Rudolph threw for one touchdown and ran for another as Oklahoma State came from behind to beat Central Michigan 24-13 Thursday night in the season opener for both teams. The Cowboys were just the fifth Power Five conference school in the last 20 years to visit Kelly/Shorts Stadium, and had to work hard to avoid becoming the first one to lose. They trailed 13-10 in the third quarter and never showed the physical dominance that a Big 12 team would expect against a Mid-American Conference opponent. Central Michigan coach John Bonamego was making his debut just 13 days after his final radiation treatment for tonsil cancer.
