Blue Jackets right wing Nathan Horton is out indefinitely with a back injury that has dogged him most of the summer. It's doubtful he'll take part in training camp and he may miss the early stages of the regular season. No, this is not an "encore" blog entry from last season.

Horton played only 36 games last season. He was out until January 1 while recovering from off-season shoulder surgery, then suffered an abdominal injury in mid-March that effectively ended his season.

The Blue Jackets will have their first training camp practice on Friday without Horton and without No. 1 center Ryan Johansen, a restricted free agent who remains unsigned. That's two-thirds of the projected top line.

"It hurts our team a little bit for (Horton) not to be 100 percent right now," Blue Jackets center Brandon Dubinsky said. "My heart goes out to him. You see the guy. You’ve been around him. He’s always got a smile on his face. He’s always happy. His energy level is infectious. All he wants to do is go out and help the team."
