Wearing a hard hat and neon vest, Louisville football coach Bobby Petrino smiled as he stood in an active construction site Tuesday and saw the future.

The ongoing expansion of Louisville’s football stadium, once said to be 10,000 seats, is actually closer to 6,000.

San Diego State University Athletic Director John David Wicker said Thursday the university’s proposed 35,000-seat Mission Valley stadium could expand to 55,000 seats to accommodate a future NFL franchise.
