Clemson defensive end Da’Quan Bowers’ pre-draft stock continues to take a hit.

One scout told SI.com’s Peter King that Bowers “failed at least two physicals that I know of” after having meniscus surgery following the college season. As King points out, three months ago Bowers was a lock to be drafted in the top-5. But if he doesn’t prove to teams that his knee is healthy at his Pro Day on Friday, there’s no telling how far he could fall.

King also had some interesting stuff to say about Auburn defensive tackle Nick Fairley, who more and more is being perceived as a “one-year wonder.” Alabama’s Marcell Dareus has already passed Fairley on most team’s draft boards (or at least presumably based on reports), but the real question is how far the former Tiger will fall. Some mock drafts projected Fairley would be taken No. 1 overall by the Panthers before the scouting combine and now it sounds like he’s not even a lock to go in the top-10.

One other tidbit from King: The Bills like Texas A&M linebacker Von Miller and Patrick Peterson “a lot.” King isn’t saying that they’ll take either player, but just that they’re high on both. I think the general consensus is that the Bills will go defense at No. 3 and wait until the middle rounds to address their need at quarterback.
