Wisconsin athletic director Barry Alvarez understands the public would like some answers. Just don't ask him for any when it comes to the Big Ten and expansion.

Alvarez said the decision rests with school presidents, not with the league's athletic directors. Even so, expansion was the hot-button topic as conference coaches and administrators gathered Monday in Chicago for three days of meetings.

"People want to know what's going on, but nobody has any answers for them," Alvarez said. "None of us do, anyway."

The Big Ten is deciding whether to expand from its current 11 members to extend the reach of its lucrative TV network and add a championship football game.

Last week, Big Ten Commissioner Jim Delany e-mailed conference officials to refute a rumor that Missouri, Nebraska, Notre Dame and Rutgers had been invited to join. Texas, Syracuse, Pittsburgh and Maryland have all been mentioned as possible targets, too.

Belmont faces post-Stakes threat

The New York Racing Association says it is running out of money and might have to shut down thoroughbred races after the Belmont Stakes in less than three weeks.

NYRA President Charlie Hayward said the state must give financial help or Belmont Park won't be able to run a full meet. He did not give a timetable for a possible closing. His comments appeared in several New York newspapers Monday.

The final leg of the Triple Crown is June 5. Belmont runs through July 18 before racing shifts to Saratoga in upstate New York on July 23.
