The Broncos have signed 36-year old CB Tyrone Poole to help out with depth in the secondary.  Poole last played in the NFL with the Raiders in 2006 so he could be rusty.  Poole has played in 142 games in his NFL career and he has made 497 tackles, has defensed 121 passes, has 6 sacks, forced 10 fumbles and he has intercepted 18 passes.  Don’t look for Poole to get a lot of playing time unless the CBs ahead of him get injured.
