Connor Murphy was placed on long-term injured reserve by the Chicago Blackhawks on Wednesday with a groin injury.
The defenseman did not play after the second period in a 2-1 shootout loss to the Vegas Golden Knights on Tuesday. Murphy missed Chicago's first game of the season with a groin injury and has no points in six games. He has 76 points (20 goals, 56 assists) in 392 NHL games with the Blackhawks and Arizona Coyotes.
Murphy had been playing on Chicago's top defense pair with Duncan Keith.
The Blackhawks recalled defenseman Dennis Gilbert from Rockford of the American Hockey League. He did not have a point in a 4-3 loss to the Philadelphia Flyers on Oct. 4 as part of the 2019 NHL Global Series in Prague, the only NHL game he's played this season.
Chicago (2-3-2) will host the Flyers on Thursday (8:30 p.m. ET; ESPN+, NBCSCH, NBCSP, NHL.TV).
