Yankees pitcher and former Husker Joba Chamberlain is fighting a 90-day license revocation after an October arrest in Lincoln for suspected drunken driving.

Chamberlain's attorney filed a petition in Lancaster County District Court Wednesday, asking that the decision to revoke his license be reviewed. Nebraska's Department of Motor Vehicles made that decision.

Attorney W. Randall Paragas of Omaha says the revocation and the law supporting it violate Chamberlain's right to due process and equal protection of the laws.

The 23-year-old pitcher hasn't been charged and is to appear in court December 17th. His blood-alcohol content level when he was pulled over for speeding on Oct. 18 was 0.134. The legal limit in Nebraska is 0.08.
