Portillo was the third-round pick, 67th overall, of the Buffalo Sabres in the 2019 NHL Entry Draft. The 24-year-old goalie has yet to play and NHL game and has spent the past two season with the Ontario Reign (AHL) after a successful tenure with the University of Michigan. Portillo will likely serve as the backup to David Rittich while Darcy Kuemper (undisclosed) is sidelined.

Los Angeles added to its goaltending depth on Sunday after they signed 23-year-old goaltender Erik Portillo to a three-year, entry-level contract. The towering 6'6" netminder was Buffalo's 2019 3rd-round pick (67th overall) and spent 2023-24 dominating the AHL with Ontario, with his 24-11-3 record, 2.50 GAA and .918 SV%.

Portillo is 19-10-2 with a .908 SV% and 3.01 GAA in 31 games played with the University of Michigan (NCAA) and has been traded for a 2023 third-round pick to the Los Angeles Kings.
