From one Cole Harbour native to another.

Colorado Avalanche forward Nathan MacKinnon is upset that his fellow Nova Scotian, Sidney Crosby, is once again dealing with concussion issues.

"It's really sad because that guy has been through wars and people don't know how much of a warrior he really is," MacKinnon told CBC News. "That's very unfortunate and it makes me upset. I don't like hearing that stuff. I'm really feeling for him."

Crosby is sidelined with a concussion after taking a hard cross-check from Washington Capitals defenseman Matt Niskanen. It marks the fourth head injury of Crosby's 12-year career.

The Penguins captain suffered his first concussion during the 2010-11 season and was limited to 41 games. Crosby played just 22 games the following year after he was diagnosed with another head injury.

Crosby has appeared in eight games this postseason, recording 11 points. He trails only teammates Evgeni Malkin and Phil Kessel in playoff scoring.
