Harkins didn't practice Monday after being diagnosed with a concussion, per Michelle Crechiolo of the Penguins' official site.

EDGE Analysis

Harkins, who was injured in Saturday's 2-1 loss to Winnipeg, will have to clear concussion protocol in order to return to the lineup. Consider him out indefinitely for now. Harkins has four assists and 59 hits over 34 games this season.

Harkins earned an assist in a 4-3 defeat to Vancouver on Thursday.

EDGE Analysis

Harkins has a helper in each of his last two contests to give him four points in his previous seven games. The winger's recent productivity follows an 18-game pointless start to the 2023-24 campaign. With Reilly Smith (upper body) suffering an injury against the Canucks, the 26-year-old Harkins could be a candidate to move into a third-line role.

Harkins picked up an assist in Monday's 4-1 win over the Flyers.

EDGE Analysis

Harkins' shot attempt went wide only for Erik Karlsson to take control of the puck and fire one home to give the Penguins an early 2-0 lead. Interestingly enough, Harkins has gone from habitually jumping between the minors and the NHL earlier in the season to sharing the ice with high-profile defensemen like Karlsson in the latest tilt. However, the 26-year-old pivot remains on the fourth line and he's more of a stopgap option with Matt Nieto (knee) expected to miss 6-to-8 weeks.

Harkins was recalled from AHL Wilkes-Barre/Scranton on Saturday.

Harkins was reassigned to AHL Wilkes-Barre/Scranton on Saturday.

EDGE Analysis

Harkins was called up earlier Saturday, but apparently the Penguins just wanted to have an emergency option on hand for warmups. With just six healthy defensemen on the roster, the team will likely activate John Ludvig (concussion) or add a blueliner prior to Sunday's game versus the Golden Knights.
