Keo was hit with a two-game suspension stemming from a DUI arrest this offseason. The Broncos released him in the midst of the suspension but they re-signed him once he was cleared to play again. Late last month, Denver cut Keo to make room for newly-acquired tight end A.J. Derby.
Keo appeared in seven games for Denver over the last two seasons. His most productive year came in 2013 while with the Texans. Appearing in all 16 games and starting 11 games at free safety, the Idaho product totaled 63 tackles, six passes defensed, and one interception.
As of this writing, the signing of Keo leaves the Saints with five safeties on the 53-man roster.
