Eddie Lack

Going into the 2009 NHL Entry Draft, he was ranked ninth among European goaltenders by the NHL Central Scouting Bureau, but went unselected. After three seasons with the Leksands IF organization, Läck moved up to the Elitserien, Sweden's premiere league, signing a two-year contract with Brynäs IF on 6 July 2009. He made his Elitserien debut on 17 October, relieving Jacob Markström (who at the time was a Florida Panthers prospect) near the end of the first period. He stopped all 18 shots he faced in a 3–2 loss to Färjestad BK. Läck went on to play in 14 games as a backup to Markström, registering a 2.67 GAA and .911 save percentage.

Läck's play garnered the attention of Vancouver Canucks scout Lars Lindgren and in the off-season, he was signed by the Canucks to a two-year, entry-level contract on 6 April 2010. He subsequently left Sweden to begin playing within the Canucks organization. Assigned to the Manitoba Moose, the Canucks' minor league affiliate, he made his American Hockey League (AHL) debut on 9 October, making 23 saves in a 5–2 win over the Rockford IceHogs. Competing for playing time with fellow Moose goaltender Tyler Weiman, Läck emerged as the team's starter, appearing in 53 games (28 wins, 21 losses and 4 overtime or shootout losses). With a 2.26 GAA (ranked seventh in the league) and .926 save percentage (fourth in the league), Läck was named to the AHL All-Rookie Team. During the 2011 Calder Cup playoffs, he helped the Moose to the second round, recording a 1.99 GAA and .932 save percentage in 12 games. Following the Manitoba's elimination to the Hamilton Bulldogs, Läck was called up to the Canucks on 13 May 2011, to travel and practice with the team as a playoff reserve. Vancouver advanced to the Stanley Cup Finals and lost to the Boston Bruins in seven games.

Positioned behind Roberto Luongo and Cory Schneider (joint winners of the 2010–11 William M. Jennings Trophy) on the Canucks' depth chart, Läck was assigned to the AHL for a second season in 2011–12. Due to the Winnipeg Jets' return to the NHL, the Moose franchise was relocated to St. John's, Newfoundland; as a result, the Canucks switched their AHL affiliation to the Chicago Wolves. Läck made his Wolves debut on 8 October 2011, stopping 31 of 33 shots in a 3–2 shootout loss to the San Antonio Rampage. He recorded his first win and shutout with Chicago three games later on 21 October against the Rockford IceHogs. The following month, Läck was called up by Vancouver after starting goaltender Roberto Luongo sustained an injury. He dressed for his first NHL game on 16 November 2011, backing up Cory Schneider in a loss against the Chicago Blackhawks before being reassigned the following day. He finished the season in Chicago posting a 21–20–3 record with a 2.31 GAA and a .925 save percentage. By season's end, he, along with backup Matt Climie, helped set a Wolves franchise record for lowest team goals against average at 2.54. Läck's second season with the Wolves started slowly, as his numbers dropped significantly from the previous season. He had been playing with a hip flexor injury and a decision was made to rest him to allow the injury to heal. The injury eventually required surgery which ended Läck's season. He finished the year playing in 13 games posting a 7–4–1 record with a 3.00 GAA and an .899 save percentage.

Läck was named the Canucks' backup goaltender to start the 2013–14 season, and made his first appearance – and recorded his first win – on 6 October 2013, with a 5–4 overtime win against the Calgary Flames. On 15 November, despite Läck having only made five NHL appearances to date, the Canucks re-signed him to a two-year contract extension worth a total of U.S.$2.3 million. He would record his first NHL shutout in his home ice debut against the Carolina Hurricanes on 9 December 2013.

On 4 March 2014, starting goaltender Roberto Luongo was traded to the Florida Panthers, along with minor leaguer Steven Anthony, for Swedish goaltender Jacob Markström and forward Shawn Matthias, making Läck and Markström (who played together for Brynäs IF) the goaltending tandem for the Canucks, and making Läck an NHL starter for the first time in his career. That summer, however, the Canucks signed Ryan Miller as their starter, but when Miller was hurt in late February 2015, Läck excelled and allowed the Canucks to maintain their playoff position, even starting the Canucks' first few playoff games. Eddie Läck recorded his first Stanley Cup playoff victory 17 April 2015, with a 4–1 victory over the Calgary Flames. Läck remained in net until he was pulled in Game 4 in Calgary, at which point Miller returned. The Canucks went on to lose their first round matchup with Calgary in 6 games.

On 27 June 2015, Läck was traded to the Carolina Hurricanes at the 2015 NHL Entry Draft in exchange for a 2015 third round pick and a 2016 seventh round pick. Prior to making his debut with the Hurricanes, he was signed to a two-year $5.5 million contract extension through to 2018 on 3 October 2015.

On 29 June 2017, Läck was traded by the Hurricanes along with Ryan Murphy and a 2019 seventh-round pick to the Calgary Flames in exchange for prospect Keegan Kanzig and sixth-round pick in 2019. On 23 November 2017, Läck was placed on waivers by the Flames with the intention of assigning him to the Flames' AHL affiliate, the Stockton Heat. He was later assigned to the Heat on 24 November 2017.

On 30 December 2017, Läck was traded to the New Jersey Devils in exchange for defenceman Dalton Prout, and was immediately assigned to the team's AHL affiliate, the Binghamton Devils. He was recalled to the NHL on 4 February 2018, to replace Ken Appleby, and made his first start as a Devil on 11 February against the Boston Bruins. On 17 February 2018, Läck made a career-high 48 saves in a 4–3 win over the Tampa Bay Lightning.

Läck was added to Swedish national team in preparation for the 2017 IIHF World Championship in Germany/France. Originally slated in the backup role to Viktor Fasth, Läck made his international debut in the round-robin stage, posting a 19-save shutout in a 2–0 victory over Latvia on 11 May 2017. With the addition of starting goaltender Henrik Lundqvist to the roster mid-tournament, Läck was subsequently demoted as Sweden's third-choice. He didn't add to his debut game as Sweden claimed the Gold Medal in a 2–1 shootout victory over Canada on 21 May 2017.

On 14 August 2019, Läck announced that he would be taking a break from playing ice hockey to focus on rehabbing his hip injury, and accepted a position as goaltender coach for Arizona State University.

On 30 March 2020, Läck announced his retirement from professional hockey following a hiatus.
