The Stanford product was hurt while pass protecting during Pittsburgh’s second possession. His right leg was twisted beneath him as he was knocked over by Bills defensive tackle Marcell Dareus.
Entering the 2012 NFL Draft, I had DeCastro graded out as one of the top seven players in the entire class. He fell to the Steelers with the 24th pick in the first round and it appeared he had already won the starting right guard spot. He has the potential to be one of the best guards in the NFL immediately and certainly has Pro Bowl potential.
Now NFL.com is now reporting that DeCastro has damage in both his right ACL and MCL and will certainly be out “a while.”
Speculation is that he has a torn ACL. If DeCastro’s injury is as bad as feared, he’ll likely miss the entire season.
That would be a serious blow to the Steelers, who are trying to rebuild their offensive line. Ramon Foster will likely move up to play right guard, with Willie Colon staying on the left side.
Slightly Good News Update: ESPN’s Adam Schefter is reporting that, though he dislocated his right kneecap, torn his MCL, and has a partially torn patellar tendon, there is no damage to DeCastro’s ACL. He is not being ruled out for the season though the Steelers are unsure if he will return this season.
Second, Slightly Worse News Update: NBC Sports is now reporting that DeCastro is out 3-5 months with his various knee injuries. So unless something amazing happens, he’s basically out until the playoffs at best.
