Just saw this on NFL network and didn't see it posted yet. Apparently he was working out privately in Atlanta while serving his 4 game suspension and tore his achilles tendon. Tough break for him, but this weakens a division rival so it's good news for us.
Nevermind, this should have been in the AFC south forum and was already reported there.
I was shocked when I read the other thread because he is currently suspended for failing a drug test. You don't normally hear about a player suffering that type of injury while he's away from the team.
It is going to be a long year for the Colts defense. Their biggesct problem at Denver was not having Mathis.
