Broncos reserve free safety Shiloh Keo was arrested for driving under the influence in Idaho early Saturday.
"We are aware of the matter involving Shiloh Keo and are in the process of reviewing it," said Patrick Smyth, the Broncos' vice president of public relations.
Keo, 28, was booked into the Ada County jail at 2:19 a.m. Saturday by the Idaho State Police. Keo recently tweeted he was heading from Denver to his offseason home in Idaho.
KBOI first reported news of his arrest.
Keo gained notoriety when the Broncos signed him late in the season after he reached out to defensive coordinator Wade Phillips on Twitter.
