Forum:KB:Shaak Ti's death

In Star Wars: The Force Unleashed, Starkiller is assigned by Darth Vader to travel to Felucia and fight his way through ferocious Rancors in order to execute Jedi Knight Shaak Ti.

However, in the deleted scenes of Star Wars Episode III: Revenge of the Sith, it is shown how General Grievous kills this Jedi Knight aboard the Separatist flagship the Invisible Hand.

Should the deleted scenes be considered non-canonic? Or is there something else as far as this topic is concerned?
