TFP first reported the two teams were discussing Carter back in January, but the Kings were also trying to pursue Blue Jackets left wing Rick Nash. After falling out of the Nash race, the Kings pulled the trigger on the Carter deal.
Carter, 27, picked up 15 goals and 10 assists for 25 points in 39 games with the Blue Jackets this season.
In 500 career NHL games with the Philadelphia Flyers and Blue Jackets, Carter has accumulated 196 goals and 172 assists for 368 points, along with a plus-40 rating and 302 penalty minutes.
Carter, who was traded to Columbus in the off-season, was originally drafted 11th overall by the Flyers in the 2003 NHL Entry Draft.
Johnson, 25, played in 61 games with the Kings this season, registering eight goals and 16 assists for 24 points.
In 343 career NHL games, all with the Kings, Johnson has accumulated 30 goals and 94 assists for 124 points, along with 256 penalty minutes. He was originally drafted third-overall by the Carolina Hurricanes in the 2005 NHL Entry Draft.
If the Kings miss playoffs this season, the first round pick moves to the 2013 NHL Entry Draft. If the Kings make the playoffs, the Blue Jackets have the option of taking Los Angeles' pick this year or wait until the 2013 draft.
