DETROIT -- Prosecutors on Tuesday formally dropped their case against the father of Chris Webber, who was accused of lying to a grand jury investigating the dealings of a former Michigan basketball booster.

U.S. District Judge Nancy Edmunds signed an order dismissing the indictments against Mayce Webber Jr., which included three counts of making false statements to the grand jury.

The reason for the dismissal, as noted in the order, was: "Weak or inadmissible sufficient evidence.''

His attorney, Robert Morgan, declined comment.

Chris Webber pleaded guilty to criminal contempt Monday, a day before his federal perjury trial was to begin. The Sacramento Kings star faces a fine, but the agreement with prosecutors is expected to allow him to avoid prison time.

Webber, a former Michigan player, had been charged with lying about money authorities say the player received from ex-booster Ed Martin.

Under the plea deal, the judge will determine the fine and decide whether the charge is a felony or a misdemeanor. Sentencing was set for Sept. 16. Prosecutors also agreed to drop the case against his father.

In court Monday, Chris Webber admitted he lied to the grand jury in 2000 when he said he didn't recall giving money to Martin. He said that in 1994, he gave Martin about $38,000 in cash as partial repayment for expenditures Martin made on his behalf.

Martin, who died Feb. 14 at age 69, pleaded guilty in 2002 to conspiracy to launder money. He admitted he took gambling money, combined it with other funds and lent it to several players while they were in school.
