He has a lacerated liver.  I guess now we know why Petrowski was signed.  I hope Ben Troupe can step up.  There has been a lot of discussion on a draft pick.  There is a stud tight end from Oklahoma State that would look good in a Titans uniform.  Troupe has been a disappointment, Hartsock and Petrowski are unknown/untested/unproven.  The guy from OSU is a very good blocker and has great hands...just a thought.
