Smith (knee) is expected to miss two or three weeks of practice while he recovers from an MCL sprain, Adam Schefter of ESPN reports.
While MCL injuries typically come with longer recovery timelines, it sounds like Smith escaped with a minor sprain, as he walked off the field without much trouble and observed the remainder of Saturday's practice after hurting his knee. The Heisman winner hasn't practiced since and now figures to miss at least half of training camp, but it sounds like he still could play in the preseason. Smith opened camp working with the starters, so the Eagles don't seem inclined to waste time with formalities or make their prized rookie jump through hoops.
