Penguins defenseman Kris Letang remains ill, and it is doubtful he will play tonight against the Phoenix Coyotes, coach Dan Bylsma said Friday.

Letang did not practice with the team at Jobing.com Arena. He sat out the Penguins' 4-1 win Thursday night against the Kings in Los Angeles.

Earlier in the season, Letang missed 19 games because of knee and elbow injuries.

Asked if he was concerned that the time out of the lineup might weigh on Letang and affect his game, Bylsma said, "I think there's some of that in his game -- thinking about the situation and different things."

Letang's ailment comes on the heels of perhaps finally settling in to a groove.

"I thought Kris' last game was an excellent game," Bylsma said of the Penguins' 3-0 win Monday night against Buffalo. "Prior to going on [this two-game] trip, I think he was excited about putting [things] together.

"I thought he was in a real good spot, a real good mentality, and he played that way."
