The 28-year-old defensive back recently tweeted he was heading home to his native Idaho. He was booked into the Ada County jail just after 2 a.m. Saturday.
“We are aware of the matter involving Shiloh Keo and are in the process of reviewing it,” Broncos VP of public relations Patrick Smyth told Renck.
Keo joined the Broncos when injuries to David Bruton, T.J. Ward and Darian Stewart exposed their safety depth, reaching out to Wade Phillips via Twitter about his interest in joining the eventual Super Bowl champions.
He played in six games for Denver after arriving in December, intercepting a pass against the Chargers in Week 17.
Originally a fifth-round pick of the Texans’ out of Texas Tech in 2011, Keo started 11 games for Houston in 2013 before being released in Sept. 2014.
