Nate Williams, a sophomore basketball player at George Washington University, has decided to attend a college closer to home, the school announced, although it said he has not yet selected a school. Williams, a 6-foot-7 forward from Willingboro, N.J., played in 26 of 29 games last season, averaging 3.8 points and three rebounds . . .

A committee of Big Ten coaches, athletic directors and conference officials is recommending a postseason basketball tournament starting with the 1988-89 season.

The panel will file its report with Big Ten athletic directors and faculty representatives Monday, but the ultimate decision rests with school presidents, said Commissioner Wayne Duke. "Never has the sentiment to hold a tournament been any higher than it is at the present time," Duke said . . .

Brigham Young cornerback Kirk Davis has been told he has Hodgkin's disease, but his chances of being cured are 96 to 99 percent, he said. The 6-foot-1, 180-pound junior has had a lump on his neck for a couple of weeks. When soreness developed, he told the team doctor, and a biopsy was performed. The disease is a cancer of the lymph nodes.

Coach LaVell Edwards said more tests will be performed this week and it will be decided if Davis will be able to play.
