Hall of Fame quarterback Warren Moon pleaded not guilty Monday to driving under the influence charges stemming from a December arrest.

Moon, who played for the Oilers, Vikings, Seahawks and Chiefs and currently works as a Seahawks radio broadcaster, was arrested on December 28 after refusing to take field sobriety and breath tests. A pretrial hearing has been scheduled for March 31, and a judge instructed Moon not to consume alcohol and to cooperate with any request that he take a blood or breath test.

The arrest was the second time in 2007 that Moon was in trouble for driving incidents involving alcohol. Moon pleaded guilty to negligent driving after an April arrest in which a police officer said Moon took “unusually shaky and deliberate steps” during a field sobriety test. Although Moon told the officer he had been drinking, he was not charged with DUI in that incident because his breath test registered .068 and .067, below the .08 legal limit for driving.

Seahawks officials have said they are conducting their own investigation of Moon. It is not known whether Moon will be retained as a team radio broadcaster.
