As Minnesota running back Adrian Peterson proved last season, ACL injuries aren’t what they used to be.

And so not quite 6 ½ months after Quenterus Smith had his torn left ACL repaired by Dr. James Andrews, the Broncos’ rookie defensive end was participating in individual and position drills the past two days.

“They told me to do what I can,’’ said Smith, a fifth-round draft pick out of Western Kentucky. “When I’m done doing the drills I feel good. I don’t feel all the way normal but I still have another month-and-a-half to get ready. They’re doing a great job with it with the little time we’ve had. But everything feels good. I don’t feel like I’m babysitting it too much.’’
