Fraser debuted with the Kings Thursday night against the Vancouver Canucks in the team's 3-2 loss.
The Kings then accused the Oilers of trading an injured player when they determined Fraser still hadn't fully recovered from a broken foot, which ended his final season in Edmonton in March. Fraser missed the first 15 games of this season while recovering from surgery.
Fraser replaced Scott Parse, who went on injured reserve Wednesday with a lower-body injury.
Veteran forward Trent Hunter also returned after a five-game injury absence.
