CRANBERRY — Pittsburgh Penguins defenseman Ryan Graves has been diagnosed with a concussion.

Coach Mike Sullivan, who announced Graves’ injury following the team’s practice at UPMC Lemieux Sports Complex Friday, did not offer a projected timeline for his return.

Graves left the Penguins’ 3-2 victory against Columbus after logging five minutes, 27 seconds of ice time during the first period.

Graves, who signed a six-year, $27 million contract with the Penguins as a free agent last July, has had a mostly disappointing season.

He was brought in with the idea of playing on one of the top two pairings, opposite either Erik Karlsson or Kris Letang, but had played his way down to the No. 3 pairing by the time he was injured.

Graves, 28, has three goals and 11 assists in 70 games in 2023-24.
