Back signed a one-year, two-way contract with Dallas on Tuesday.

Back collected seven goals and 36 points in 59 regular-season contests for AHL Texas in 2023-24. The 24-year-old forward doesn't have any NHL experience yet. Back will probably spend most, if not all, of the 2024-25 campaign in the minors.

San Jose acquired Walman and a 2024 second-round pick from Detroit on Tuesday in exchange for future considerations.

Walman produced 12 goals, 21 points, 108 shots on net and 151 blocked shots in 63 games during the 2023-24 campaign. The 28-year-old defender has two more seasons left on his three-year, $10.2 million contract. As a member of the Sharks, Walman could occupy a top-four role and see power-play time.

Kolyachonok signed a two-year contract with Utah on Tuesday.

Kolyachonok earned one goal, three assists, five shots on net, six blocked shots and four hits in five NHL outings this past season. He also collected eight goals and 11 points in 36 regular-season contests for AHL Tucson during the 2023-24 campaign. He will compete for a depth spot on the Utah blue line during training camp in the fall.

Mittelstadt signed a three-year, $17.25 million deal with Colorado on Tuesday.

Mittelstadt put up solid numbers for the Avs after being acquired at the trade deadline last season. The 25-year-old center garnered four goals on 25 shots to go with six helpers, 12 hits and eight blocks in 18 regular-season appearances. Previously scheduled to be a restricted free agent this offseason, Mittelstadt avoids a protracted contract negotiation by getting this deal done early. Heading into the 2024-25 campaign, the Minnesota native should be capable of reaching the 50-point threshold for a third consecutive season and even challenging for 60-plus.

DeMelo inked a four-year, $19.6 million contract with Winnipeg on Tuesday.

DeMelo was able to get a new deal signed ahead of the start of free agency Monday, tying himself to the Jets for another four seasons. Last year, the veteran blueliner played in all 82 regular-season contests while putting up three goals, 28 assists and 83 shots. While DeMelo is never going to be a Norris Trophy candidate, he should be able to replicate that production next season, making him a decent mid-range fantasy target.

Ceci posted an assist and two hits in Monday's 2-1 loss to the Panthers in Game 7.

Ceci set up a breakaway goal for Mattias Janmark in the first period. The helper ended a nine-game drought for Ceci, who was also scratched in Game 2 of the Stanley Cup Finals. The 30-year-old defenseman had five points, 24 shots on net, 37 hits, 30 blocked shots and a minus-5 rating over 24 playoff outings. He's under contract for 2024-25, but with that being the last year on his deal, the Oilers may shop him around if they want to remodel their blue line.

Janmark scored a goal in Monday's 2-1 loss to the Panthers in Game 7.

Janmark had four points over the last four games, but the Oilers weren't able to complete a comeback for the ages. The 31-year-old forward produced eight points in 25 playoff outings after being limited to 12 points in 71 regular-season contests. He's one of seven NHL-level unrestricted free-agent forwards for the Oilers, and it's unclear if he'll re-sign with the team. Janmark's defensive skills could make him a coveted depth option for any number of teams if he makes it to the market July 1.

Skinner stopped 19 of 21 shots in Monday's 2-1 loss to the Panthers in Game 7.

Skinner was unable to extend his winning streak to four games, and the Oilers ended up a win shy of the Stanley Cup. While there were some rough patches for Skinner this postseason, he ended up with a 14-9 record, a 2.45 GAA and a .901 save percentage over 23 appearances. The 25-year-old looks firmly entrenched as the Oilers' starting goalie heading into 2024-25.

Kulikov notched an assist in Monday's 2-1 win over the Oilers in Game 7.

Kulikov's only two points in the playoffs were both assists, and they came in the last two games. The defenseman added 56 hits, 25 blocked shots and a minus-1 rating while playing in a bottom-pairing role over 24 postseason appearances. The 33-year-old is set to be an unrestricted free agent this summer, one of three regulars on the Panthers' blue line that could hit the open market July 1.

Lundell registered an assist in Monday's 2-1 win over the Oilers in Game 7.

Lundell didn't score a goal in June, but he had six assists over eight contests. The 22-year-old center wrapped up the postseason with 17 points, 29 shots on net, 44 hits, 17 blocked shots and a plus-8 rating while playing in a key two-way role on the third line. He's set to be a restricted free agent this summer after reaching the end of his entry-level deal, and it's likely the Panthers find a way to keep him around.
