There is only one certainty about the New Orleans Saints’ future: They will live and work out of the Marriott Riverwalk in San Antonio for a while.

Beyond that, question marks abound. It’s highly unlikely they’ll be able to hold their home opener Sept. 18 at the Superdome – and they may not be able to play there at all this season after the stadium was ravaged by Hurricane Katrina. So that first game against the New York Giants could be at the Alamodome in San Antonio. Or at Tiger Stadium in Baton Rouge, La. Or even at Legion Field in Birmingham, Ala.

And all of those sites could play host to other home games for the Saints, who escaped the hurricane by flying with their families last weekend to San Jose, Calif. New Orleans plays at Oakland tonight in its final exhibition game.

While the Saints and NFL officials have been discussing a variety of alternatives, they haven’t talked yet with many of the people at the proposed sites.

“We can say, is LSU an option, yeah, but is it an option with them?” Saints spokesman Greg Bensel said Wednesday by phone from San Jose. “That’s the next hurdle. We haven’t crossed that hurdle yet.”

Only one hurdle has been crossed.

Following the Raiders game, the Saints will go to San Antonio, where they will stay at the same hotel they stayed at last season when Hurricane Ivan chased them out of New Orleans in the second week of the regular season.

Green undergoes procedure

Kansas City, Mo. – Chiefs quarterback Trent Green underwent an outpatient procedure to improve circulation in his leg but will be ready for the season opener on Sept. 11, Kansas City coach Dick Vermeil said Wednesday.

Green, who’s been having numbness in the lower left leg and foot, will not play Friday night when the Chiefs meet St. Louis in their final preseason game. Vermeil said Green, who played only two series last weekend against Seattle, did not have a blood clot.

“He had a little problem. It was a minor problem and it’s taken care of,” Vermeil said.

Vermeil said it was not major surgery and that Green would be at the stadium today for team meetings and return to practice Monday.
