The defending Stanley Cup champions made the move Monday before travelling to Dallas to face the Stars on Tuesday night.
Penner missed the Kings' past four games with a lower-body injury after getting hurt March 31 in Dallas. The eight-year NHL veteran has two goals and nine assists in 25 games this season.
The Kings began Monday in a third-place tie with Vancouver in the overall Western Conference standings. Los Angeles trails Pacific Division-leading Anaheim by nine points after Sunday's 4-3 shootout loss to the Ducks.
[Stamkos] is a great teammate and a great leader, that's why he's got the 'C'. He brings that tremendous work ethic to the rink and he's one of the top players in the game. I know if I put the passes where they are supposed to be, there's a very good chance he's going to put it in the back of the net.
— Lightning forward Jonathan Drouin
