UPDATED: Letang (Lower-Body), Acciari (Upper-Body) Injured

CRANBERRY — Two Pittsburgh Penguins regulars, top-four defenseman Kris Letang and fourth-line center Noel Acciari, sat out practice at UPMC Lemieux Sports Complex and are being evaluated for injuries.

Coach Mike Sullivan said Letang has a lower-body injury and Acciari has an upper-body issue, but offered no other details.

“That’s all I’ve got for you,” he said.

Letang and Acciari both played in the Penguins’ 6-3 loss at Detroit Wednesday evening.

The Penguins have not lost any man-games to injury so far this season.

Ryan Shea moved into Letang’s usual spot alongside Ryan Graves during drills. Because they are carrying only 12 forwards on the major-league roster, there was no one to fill in for Acciari on the fourth line, so injured defenseman Will Butcher was used there.

Matt Nieto, who had been used primarily on the left side of the fourth line, flipped spots with Jansen Harkins, who had been the right winger on the third line. The Penguins’ personnel groupings were otherwise unchanged:

Guentzel-Crosby-Rust

Smith-Malkin-Rakell

O’Connor-Eller-Nieto

Harkins-Carter-(Butcher)

Pettersson-Karlsson

Graves-Shea

Joseph-Ruhwedel-(Ludvig)
