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

He will be out seven to 10 days.

It is the same shoulder that Nugent-Hopkins first injured on Jan. 2 when he fell into the boards in a game against the Chicago Blackhawks.

"It's the same area, same shoulder, but a new thing on top," Nugent-Hopkins said on Tuesday. "Compared to the first one, it's not even close … so hopefully I can get back sooner, rather than later.""
