Graves (concussion) will not be in the lineup to face Detroit on Thursday, Dan Kingerski of PittsburghHockeyNow.com reports.

EDGE Analysis

Graves will be shelved for his seventh straight game due to a concussion suffered against Columbus on March 28. Still, the blueliner has started skating and could be an option at some point before the end of the regular season. However, the play of Ryan Shea and Jack St. Ivany could relegate Graves to a spot in the press box even once he's given the all-clear.

Graves was diagnosed with a concussion Friday, according to Michelle Crechiolo of the Penguins' official site.

EDGE Analysis

Graves was injured late in the first period Thursday versus Columbus and did not return. The 28-year-old blueliner has three goals, 11 assists, 72 hits and 142 blocked shots in 70 appearances this season. John Ludvig will likely replace Graves in the lineup Saturday, as the Penguins get a return match against Columbus. Graves should miss at least a week with the concussion, and it's possible that his season could be over.

Graves is being evaluated for an upper-body injury after leaving Thursday's game versus the Blue Jackets following the first period.

EDGE Analysis

Graves logged just 5:27 of ice time in the contest. If he is unable to play Saturday in a rematch in Columbus, John Ludvig will likely enter the lineup.

Graves (personal) returned to practice ahead of Tuesday's matchup with Carolina, freelance Penguins' reporter Shelly Anderson reports.

EDGE Analysis

Graves missed Pittsburgh's two-game road trip following the birth of his child but is back on the ice ahead of Tuesday's tilt. Graves figures to reclaim his spot on the third pairing alongside John Ludvig, which will likely see Jack St. Ivany relegated to the press box or possibly returned to AHL Wilkes-Barre/Scranton. Considering Graves' minimal offensive impact this season, 14 points in 68 games, few fantasy players will have anxiously awaited his return.

Graves is back in Pittsburgh awaiting the birth of his child and will miss out against Dallas on Friday, Penguins play-by-play announcer Josh Getzoff reports.

EDGE Analysis

Depending on timing, it's possible Graves will link up with the team to face Colorado on Sunday, but for now, he should probably be considered questionable at best. Considering the defenseman has just one point in his last eight outings, few fantasy players figure to be impacted by his absence. In his stead, Jack St. Ivany will make his NHL debut versus the Stars.

Graves picked up two assists in Tuesday's 5-3 win over the Blue Jackets.

EDGE Analysis

Both helpers came in the first period, giving the 28-year-old blueliner his first multi-point performance since Nov. 11. Graves hasn't scored a goal in 17 straight games, and his fantasy value comes from other categories -- on the season he has three goals and 13 points in 60 contests, but that offense comes with 61 hits, 119 blocked shots and a plus-12 rating.

Graves logged an assist and blocked three shots in Saturday's 4-3 loss to the Flames.

EDGE Analysis

Graves has earned three assists over 12 games since the All-Star break. The 28-year-old defenseman's third-pairing role -- one he ended up in after displaying uncharacteristically weak defense early in the season -- has done nothing to help his offense. Graves has 11 points, 68 shots on net, 111 blocked shots, 59 hits and a plus-11 rating over 58 appearances, but it doesn't look like he has an obvious path back to a top-four role.

Graves scored a goal on one shot in Thursday's 6-5 victory over the Bruins.

EDGE Analysis

Graves' 19-game goal drought came to a close with his tally Thursday. It was just the second goal of the year for the defenseman, who is well off a 20-point pace after having reached that mark in each of the previous two campaigns. The Nova Scotia native has also underwhelmed defensively, which has led to him dropping to the third pairing.

Graves tallied a goal, a hit and three blocked shots in Sunday's 3-0 win over the Golden Knights.

EDGE Analysis

Graves opened the scoring early Sunday, firing a loose puck past Adin Hill 2:13 into the first period for his first goal of the season. The tally would stand as the game-winner. The 28-year-old Graves is averaging a career-high 21:31 of ice time on the Penguins' top pairing this season, though he's not likely to offer consistent production offensively. He has just three points (a goal and two assists) in his last 13 contests and has yet to top 30 points in his six-year NHL career.

Graves earned two assists along with four blocked shots in Saturday's 4-0 win over the Sabres.

EDGE Analysis

Graves continues to carve out a substantial role on the Penguins blue line, as he's averaging a career-high 21:25 of ice time on the top pair with Kris Letang. However, Graves is not included on the man advantage, acting as the dedicated stay-at-home defender in that duo at even strength and on the penalty kill. With that said, his two-apple delivery from Saturday reminds us that he's capable of helping out offensively in a pinch.
