The NFL has suspended linebacker Mario Haggan for 4 games for violating the league’s banned substance policy.  Haggan played in all 16 games for the Bills last season and he made 20 tackles and had 1 sack.  Haggan has now played in 65 games in his NFL career and he has made 79 tackles, has 1 sack and he has forced 2 fumbles.  This will hurt the linebackers’ standing with the Bills.
