Ruff diagnosed with concussion after fall in practice Tuesday

Players aren't the only ones susceptible to injuries at the rink.

New York Rangers assistant coach Lindy Ruff was diagnosed with a concussion after stepping on a puck and hitting his head in practice Tuesday, head coach Alain Vigneault told reporters Wednesday, according to NHL.com's Tom Gulitti.

Ruff was not with the team in Washington, D.C., for Wednesday's game against the Capitals, and Vigneault said Ruff needed stitches after the fall.

Vigneault added that the former Buffalo Sabres and Dallas Stars head coach was hospitalized but should be back soon, according to Stephen Whyno of The Associated Press.

Ruff joined the Rangers' coaching staff in July.
