The Broncos have released linebacker Nick Greisen.  He was on the Broncos’ roster last season but he never played a down for them due to a torn ACL.  The Broncos didn’t want to wait for Greisen anymore.  Greisen has played in 7 years in his NFL career appearing in 98 games in which he has 255 tackles, 13 passes defensed, 4 sacks, 5 forced fumbles and 1 interception.  The Broncos won’t miss Greisen in 2010.
