Moreno, 24, was driving southbound on Interstate 25 Feb. 1 when police pulled him over for going more than 70 mph in a 45 mph construction zone. The officer said he smelled alcohol when he approached Moreno's Bentley convertible, decked out with personalized plates that read, "SAUCED."
Moreno performed badly on a roadside sobriety test and a Breathalyzer test, and was arrested for driving under the influence, KDVR-TV, Denver, reported.
The Broncos issued a statement Monday saying, "We take the incident involving Moreno very seriously and are thoroughly reviewing this matter."
Moreno's agent did not respond to calls for comment, KDVR said.
