Penguins' Daley week to week with injury suffered Friday

The Pittsburgh Penguins' blue line is thinning out by the day.

Trevor Daley is considered week to week with what the Penguins are calling an "upper-body injury," head coach Mike Sullivan said Saturday.

Daley was forced to leave Friday's loss to the Los Angeles Kings with what was a fully undisclosed ailment at the time.

Kris Letang was placed on injured reserve earlier Saturday after he was ruled out for "a couple of weeks" Thursday with an injury of his own.
