The Blue Jackets get right wing Matt Frattin and a second-round pick in the 2014 draft, plus a conditional third-rounder if the Kings win their first-round playoff series or re-sign Gaborik.
The 32-year-old Gaborik will be a free agent after the season. He was making $7.5 million a year, with the Blue Jackets expected to pick up a portion of the $1.9 million in remaining salary. He has missed games with a sprained knee and a broken collarbone this season, limiting him to just 22 games, but is healthy for the stretch run.
The 26-year-old Frattin has two goals and four assists in 40 games.
