Dec. 8 (UPI) -- The Pittsburgh Penguins announced Wednesday that star winger Jake Guentzel is "week-to-week" with an undisclosed upper-body injury.
Penguins head coach Mike Sullivan declined to provide specifics about how or when Guentzel was injured. Guentzel briefly left the ice during the first period of Pittsburgh's 6-1 win over the Seattle Kraken on Monday night, though he returned and finished with two goals and an assist.
