The Texans have signed 34-year old safety Brian Russell.  Russell played in 9 games for the Jaguars this season making 12 tackles.  He has now played in 117 games in his NFL career and he has made 474 tackles, defensed 39 passes, has 3 sacks, forced 3 fumbles and he has 16 interceptions.  Russell should be able to help the Texans out on special teams and give them depth at safety.
