Just a day removed from recording the go-ahead goal in a win over the Calgary Flames, Theodore potted the game-winner in overtime for the Vegas Golden Knights against the Oilers.
Both wins were huge and, as a result, the Golden Knights extended their lead at the top of the Pacific Division to three points with 11 games to go.
The Knights were handed a sizeable boost prior to faceoff at Rogers Place after Oilers superstar Connor McDavid was ruled out because of illness.
However, despite missing their face of the franchise, Edmonton still landed the first blow of the night after Alex Chiasson set up a screen in-front of Marc-Andre Fleury before redirecting a shot into the net.
