Derrick Green & Brennen Beyer with "boo-boo" & should be back soon

Submitted by Leaders And Best on
I thought I would update the Derrick Green injury saga with the latest from Hoke's presser.
 

Hoke post-Thursday practice: Beyer and D Green "little boo boos". Expects them back Saturday

Also on another note, Florida LB Matt Rolin tore his ACL again today. It's the one thing I am kind of worried about if we try to rush Jake Ryan back.

As far as the ACL itself, a surgically reconstructed ACL usually has approximately 80% of its tensile strength at 8 months.  Studies have yet to nail down definitive predictors which make a player more or less likely to reinjure in return to sport, and the evidence is unclear whether or not an accelerated rehab protocol results in a higher rate of reinjury in return to sport when compared to the more conservative 8-12 month rehab.  So there's that.

A player's biomechanics, specifically how the player loads through the knee while making athletic movements PRIOR to injury is a good indicator (though hard to measure) of how likely a player is to reinjure.  A good example of this would be Derick Rose (bad) vs. Wes Welker (good).  

Obviously in football there are outside forces outside of a player's control that can cause an injury, but since JMFR is usually the one doing the hitting as opposed to taking them I believe that he has a good chance to stay healthy assuming he is doing well with his rehab.

That's not an entirely accurate statement.  Yes, the donor ligament or tendon is extremely strong for the first 3-4 weeks after surgery.  After 4 weeks, the donor ligament is actually made quite weak during the early process of collagen fiber remodelling.  With rehab and time, the fibers become reoriented in a way to optimize tensile strength.  100% remodelling of the ACL takes 12-24 months depending on the age, activity level, general health, etc.

In the end, a surgically reconstructed ACL is no stronger than a fully healed non-reconstructed ACL.  The difference with a reconstructed ACL is that the timetable for healing is well established taking out the uncertaininy that comes with trying to rehab a non-reconstructed torn ACL.

Nick Baumgardner backs that up here - LINK. Regarding Green:

The 5-foot-11, 240-pound bruiser isn't expected to miss significant time, Hoke said, but any missed on-field action is a notable setback to his development. "It always makes it more difficult if you lose reps," Hoke said. "Just the experience and terminology and everything else."

For both Green and Beyer, it is at least encouraging to hear that they won't miss a lot of time. Hopefully, they are right back out there as soon as possible.

So the whole "out two weeks" was a bit premature? Possibly like your rem cycle?

It was old, and lame, about the second time he ran that up the flagpole.

Please, Coach Hoke; just say that the Michigan coaching staff will not discuss injuries unless and until players will miss games.  Say it like an adult.  Be brusque with the press if this is the policy that you wish to pursue and you feel you must shut off the discussion.  But please don't take it out on the English language.  And whatever you do, please don't lie to television reporters about injuries.
