The mystery injury keeping Buffalo Bills outside linebacker Manny Lawson out of training camp appears to be a partially torn pectoral muscle, according to Mark Ludwiczak of Bills Digest.
Manny Lawson told me he thinks he'll be back by Week 1. Has a partially torn pectoral muscle, not completely torn. Great news for Bills.

Lawson doesn’t think the injury is serious enough to keep him out of any regular season games. Lawson was placed on the Active/Non-Football Injury list prior to training camp, stemming from an injury he suffered while working out.
