The Saints have lost linebacker Mark Simoneau for the season due to a serious back injury.  This will hurt the depth in the linebacking unit as Simoneau was the top backup there for the Saints.  He played in all 16 games for the Saints last season and he made 70 tackles, defensed 1 pass and he had 2 sacks.  Simoneau has played in 32 games for the Saints the last two years and he made 131 tackles, defensed 2 passes, had 3 sacks and 1 interception.  He will be missed, especially if the Saints suffer any more injuries in the linebacking corps.
