Pittsburgh Penguins head coach Dan Bylsma ankle sprain and will possibly be sidelined at least a month.

"After a week we'll have a better idea of what the time frame looks like exactly, as it calms down over the next week or so and as he rehabs," Bylsma said. "Right now we're looking at 4-to-6 weeks."

Kennedy sustained the injury late in the Penguins' 5-2 loss Sunday at New Jersey.

In 42 games this season, the 25-year-old has six goals and 16 assists.
