The Senators had to play one man short in their season opener because MacEwen was out, but he'll make his season debut on Saturday, giving the Senators a full lineup. MacEwen split his 2022-23 season between the Flyers and Kings, posting 10 points (4G / 6A), 150 hits, 66 PIMS and a minus-11 rating in 55 games.

MacEwen missed the Senators' opening night game due to an upper-body injury and will be a game-time decision for their second matchup of the season vs. Philadelphia. The 27-year-old bruising right-winger had four goals, six assists, 66 PIMs, 73 SOG, and a -11 plus/minus through 56 games with Philadelphia and Los Angeles in 2022-23.

Ullmark is coming off a remarkable season that saw him win the Vezina Trophy and post an absurd 1.89 GAA and .938 SV% in 49 appearances (40-6-1). Like last season, the talented Swedish goaltender should see a near-split in the crease with counterpart Jeremy Swayman but at least for the Bruins' season opener, the nod goes to Ullmark. The Bruins, who allowed the fewest goals in the league last season, are facing a Blackhawks team that travelled from Pittsburgh last night after defeating the Penguins 4-2. Despite the Blackhawks having rookie phenom Connor Bedard in the lineup, the Bruins are still massive -310 home favourites.

If MacEwen is unable to play in the season opener, the Senators will likely have to play with only 11 forwards. MacEwen recorded 10 points last season (4G / 6A) and 66 PIM across 56 games between the Philadelphia Flyers and Los Angeles Kings last season.

Jenik had seven goals, 16 assists, 50 PIMs and a +3 plus/minus with the Tucson Roadrunners in 2022-23 and has signed a one-year, two-way contract extension with Arizona worth $775,000. The 23-year-old forward had appeared in 17 games for the Coyotes across the previous three seasons, picking up four goals and an assist. He was the Coyotes 2018 third-round Draft Pick (65th overall) and will be hoping to stick with the big club for a full season.

Del Zotto played for eight NHL teams across 13 seasons and announced his retirement from professional hockey on Wednesday. The 33-year-old closes out his career with 63 goals, 199 assists, 284 PIMs, 1074 SOG, and a -30 plus/minus across 736 NHL games played. Del Zotto broke into the NHL with the New York Rangers after being a first-round pick in the 2008 NHL Entry Draft (20th overall).

Sanderson enjoyed a very successful rookie season in 2022-23 as he finished his inaugural campaign with four goals, 28 assists, 132 SOG, 12 PIMs, and a -6 plus/minus through 77 games played and has signed an eight-year, $64.4 million ($8,050,000 AAV) contract extension. The 21-year-old defenseman was Ottawa's 2020 1st round-pick (5th overall) and is expected to take a massive leap forward in his sophomore campaign.

Sebrango was a third-round pick in the 2020 NHL Entry Draft and split the 2023 season between Grand Rapids (AHL) and Toledo (ECHL). The 21-year-old was fairly deep on the Red Wings' defensive prospect depth chart, so it's not a huge loss for an organization that has invested a lot of draft capital in defensemen in recent years. During his time in the AHL, Sebrango had five goals and 13 assists (18 points) in 135 games over the last three seasons.

MacEwen had four goals, six assists, 64 PIMs, 73 SOG, and -11 plus/minus through 56 games with both Philadelphia and Los Angeles and has signed a three-year, 2.325 million contract with the Ottawa Senators. The 26-year-old bruiser adds some fourth-line depth to the Senators and brings 13 goals, 28 points and 245 PIMs across 186 career NHL games to nations capital.

Pilon had 11 goals, 18 assists, 24 PIMs and a +6 plus/minus through 53 games with Hershey (AHL) in 2022-23 and has signed a one-year, two-way contract worth $775,000. The 25-year-old centre brings a goal and three games of NHL experience to the Senators after being a third-round pick (87th overall) in 2016 to Washington.

Highmore had 19 goals, 42 assists, 34 PIMs and a +1 plus/minus through 68 games in 2022-23 with Springfield (AHL) and has signed a one-year, two-way contract worth $775,000 with Otttawa.

The 23-year-old left-winger was acquired by San Jose at the trade deadline in the mega deal which saw Timo Meier head back to New Jersey.

Larsson spent most of 2023 in the AHL, where he had 17 points (4G / 13A) in 55 games with Belleville. During his time with Ottawa, he was held pointless with four shots and seven hits in seven games. It sounds like the Senators couldn't get Travis Hamonic re-signed, so they re-signed Larsson to maintain the blueline depth.

Davies had 11 goals, 12 assists, 90 PIMs and a +4 plus/minus through 66 games with Rochester (AHL) in 2022-23 and has signed a one-year, two-way contract through the 2023-24 season.
