Injury Notes: Sabres, Penguins, Ryan, Jarnkrok

The Buffalo Sabres’ depth will be tested just two games into the season, with top-six wingers John-Jason Peterka (concussion) and Zach Benson (lower-body) both facing injury, per Lance Lysowski of The Buffalo News. No timeline was provided for either player. Benson was held out of the team’s Saturday morning game in favor of top prospect Jiri Kulich, while Peterka exited the game after just three shifts. Lysowski added that team captain Rasmus Dahlin also seems unhealthy, despite being the team’s clear-cut top defender through their first two games.

The menagerie of injuries is weighing heavily on the Sabres, who lost both games in the Prague series by a combined score of 7-2. Peterka recorded the primary assist on Buffalo’s first goal of the year – making a strong play behind the net to set up Owen Power in the slot. Those are the hard-nosed plays Peterka has become known for in his early career, a big part of how he managed 28 goals and 50 points last season. Despite being in his age-18 season, Benson wasn’t too far behind – netting 11 goals and 30 points of his own, though he did miss 11 games to injury last year. Both players are not only core pieces of the present Sabres lineup, but pillars of the team’s future. Their healthy and speedy recovery will be paramount as the team looks to find their bearings when they return to America.

Other injury updates from around the league:

• The Pittsburgh Penguins are also bearing through a pair of injuries, with both Bryan Rust and Vasiliy Ponomarev listed as day-to-day per Seth Rorabaugh of The Athletic. No details or timeline were provided. Rust has missed the bulk of Pittsburgh’s preseasons with what were originally described as maintenance days, before this injury designation. He’ll have his eyes set on the team’s top line when he returns to full health, having posted a commendable 56 points – split evenly – in just 62 appearances last year. Ponomarev doesn’t have the same lineup security, though his 30 points in 43 AHL games last season could be enough to warrant a test in the bottom-six. Any bout with the Penguins would be notable for the 23-year-old Ponomarev, who made his NHL debut with Carolina last season – scoring two points in two games.
