Penguins defenseman Kris Letang will miss tonight's game against the New York Islanders at Consol Energy Center because of an unspecified injury that apparently is not concussion-related, coach Dan Bylsma said.
Letang is out on a day-to-day basis.
Bylsma also said defenseman Ben Lovejoy had arthroscopic knee surgery today and will be out three to four weeks.
Defensemen Simon Despres and Brian Strait were recalled Monday from the American Hockey League and will be in the lineup tonight.
Letang, the team's top defenseman, got banged up twice in Sunday's 5-2 win over New Jersey. He left for several minutes at one point and was evaluated by doctors to rule out concussion symptoms, but finished the game.
He missed nearly two months earlier in the season because of a concussion and, earlier this month, missed another five games because of recurring symptoms.
Lovejoy left in the first period of Sunday's game. He has served primarily as the Penguins' seventh defenseman but was playing because of an undisclosed injury to defenseman Matt Niskanen.
Niskanen and center Joe Vitale, who is believed to have a shoulder injury, worked out on the ice before the team's morning skate and remains day-to-day.
Winger Steve Sullivan, who missed Sunday's game because of an undisclosed injury, is expected to return tonight. He said it was something that just needed a couple of days of rest.
