"After returning for just two games, Edmonton Oilers rookie Ryan Nugent-Hopkins is back on the shelf.

The team announced on Tuesday that he'll be out seven to 10 days with a sprained left shoulder. It is the same shoulder that he first injured on Jan. 2 when he fell into the boards in a game against the Chicago Blackhawks.

"It's the same shoulder but a different injury," said Nugent-Hopkins. "It's not close to my first shoulder injury. I could feel it as soon as I got hit — my shoulder kind of dropped."
