The Seahawks have likely lost starting inside linebacker Lofa Tatupu for the remainder of the season due to a torn pectoral muscle.  He likely ends this season with 32 tackles, 1 tackle for a loss and 2 passes defensed.  David Hawthorne will likely replace him and he has had a solid year so far with 27 tackles, 3 tackles for a loss, 1 pass defensed and 1 interception.  Hawthorne will likely do a decent job replacing Tatupu but this really hurts the linebacker depth of the Seahawks.
