NEW ORLEANS — What was billed as the return of football to the Tulane campus turned into a successful homecoming for Georgia Tech's Tony Zenon Saturday. Zenon and Tim Byerly each rushed for two touchdowns to lead the Yellow Jackets to a 38-21 victory over the Green Wave in the first game at Yulman Stadium. Zenon, a fifth-year senior running back who had 45 family members in attendance, was an eighth-grade student at St. Augustine High School in New Orleans when Hurricane Katrina struck.
