Kris Letang's injury appears to be a bit worse than originally thought.

Pittsburgh Penguins head coach Mike Sullivan told reporters Saturday that his star defenseman is going to need some extra time to recover.

"It's a little more complicated than day to day," he said. "We're just hoping it's not a long-term injury."

Letang was initially deemed day to day with what the club would only refer to as an upper-body ailment. He's missed the last four games and has been limited to 41 of Pittsburgh's 63 contests with various injuries.
