Jaromir Jagr participated in his first full practice on Friday since sustaining a back/hip injury. Jagr didn't end up playing in a single preseason game, but he still is projected to play in the season opener. He might get off to a sluggish start to the season because of that, but his health is also an ongoing concern. Even if he doesn't suffer a significant injury this season, a collection of day-to-day injuries could add up throughout the campaign.
