Tim Donaghy lost his high-paying job as an NBA referee, the respect of his colleagues and possibly his freedom.

Now, as he awaits sentencing in federal court for participating in an illegal betting operation, Donaghy might also lose his wife, his Florida home and the custody of his children.

Donaghy's wife, Kimberly, filed for divorce Thursday in Manatee County (Fla.) Court, claiming that their 12-year marriage is "irretrievably broken." She wants alimony, custody of their four girls, ages 6 to 11, and the lion's share of their marital assets.

Kimberly Donaghy says in court papers that her husband's "voluntary actions have resulted in his loss of income" ? $260,000 a year, to be exact ? as an NBA referee.
