Lofton was one of about a hundred spectators on Monday as the New Orleans Saints opened preseason football practice at Southeastern's campus.

''We played before some smaller crowds than this,'' Lofton said.

BIRMINGHAM, Ala. (AP) - Boyd McWhorter, the retiring commissioner of the Southeastern Conference, was listed in fair condition following the removal of a bladder tumor.

Marguerite McWhorter said her husband entered St. Vincent's Hospital in Birmingham Sunday and underwent an operative procedure Monday morning that did not require incisions.

''He's doing very well, we're very pleased,'' Mrs. McWhorter said Monday night. ''If there are no problems, and if everything goes well, he should be home by Wednesday or Thursday.''

Hamp McWhorter, McWhorter's son, said doctors had not determined whether the bladder tumor was malignant or benign.

The 63-year-old McWhorter, commissioner of the SEC since 1972, earlier this year announced his retirement effective Aug. 31. A successor has not been named.
