Michigan State senior basketball guard Scott Skiles was ordered to serve a 30-day jail term for violating probation on a 1985 misdemeanor drug conviction when he was arrested Nov. 7 in East Lansing, Mich., on a charge of drunken driving. Skiles has pleaded innocent to the charge. His jail term will be divided between spring break and a period after the school year . . .

Additional sexual assault charges were filed against three former University of Minnesota players who were arraigned in Madison, Wis., on charges of repeatedly raping a Madison woman Jan. 24 after a basketball game at the University of Wisconsin.

Mitchell Lee, 21, Kevin Smith, 21, and George Williams, 19, remained silent when Dane County Circuit Judge George Northrup asked how they pleaded. He then entered not guilty pleas on their behalf.

Charges against Lee were increased to six counts of first-degree sexual assault, and he faces a maximum 120-year prison sentence if convicted of all charges. Smith's charges were increased to four counts of first-degree sexual assault with a maximum sentence of 80 years. Williams faces two counts of first-degree sexual assault, with a maximum penalty of 20 years. The new charges were based on a sexual assault statute concerning multiple assailants.
