The Devils will open the season without their No. 1 center, Travis Zajac, who will be out until mid-November following Achilles tendon repair Thursday.

"There's no panic. That's what we have depth for, and a minor-league system," GM Lou Lamoriello said.

"It had to be repaired, so it was torn," said Lamoriello, who said he did not know whether the vital tendon in his left calf was severed.
