The Broncos have signed 30-year old inside linebacker Andra Davis to a undisclosed deal.  Davis played in all 16 games for the Browns last season and he made 90 tackles, defensed 3 passes and he had 1 interception.  Davis has now played in 105 games in his 7 year NFL career and he has made 642 tackles, defensed 26 passes, has 8.5 sacks, forced 4 fumbles and he has intercepted 8 passes.  Davis should help improve the run defense for the Broncos.
