The Oilers announced the deal Tuesday night.
Cammalleri, 35, is in his 15th season and had three goals and four assists in 15 games since joining the Kings as a free agent this summer. This will be Cammalleri’s third stint in Alberta. He played for the Calgary Flames twice — in 2008-09, and again from 2011 to 2014.
Cammalleri has 290 career goals and 330 assists over 855 NHL games.
Jokinen, 34, has one assist in 14 games with Edmonton this season. The Oilers signed Jokinen to a one-year deal as a free agent in July.
