Naturally, folks are assuming Robert Griffin III will make an Adrian Peterson-like recovery from his recent knee reconstruction operation.

A new report, however, throws cold water all over that notion.

A league source tells ProFootballTalk.com that there is "much greater concern" surrounding RG3's right knee, more so than "anyone connected to the Redskins or Griffin" would like to admit.

There are several apparent reasons that spark apprehension and pessimism:

  1. Griffin tore his ACL and LCL, meaning he'll have to rehab both ligaments simultaneously.
  2. Doctors had to use a patellar tendon graft from his healthy left knee to fix his damaged right.
  3. In addition to the ACL and LCL, Griffin partially ruptured his meniscus.

Though, the "biggest concern" stems from the quarterback's knee cartilage. Griffin has undergone three surgeries in as many years, dwindling the amount of remaining cartilage and tissue. The worst case scenario would be a bone-on-bone condition, which requires extensive surgeries and is known to shorten -- or perhaps end -- an athlete's career.

While Griffin, 22, still is very young, and a seemingly quick healer, it shouldn't be expected that he'll pull through like Peterson, who is a very rare exception and physical specimen. There's a reason why Dr. James Andrews, a world-renowned surgeon, refused to make any guarantees for next season after he worked on Griffin. This may be it.

Even if he does return for the 2013 season opener, Griffin seems likely to constantly be under the microscope -- both figuratively and literally -- for the duration of his career.
