"That starts to then threaten their ability to do their job and actually take care of their patients because of all the infighting," Henderson explained. "It becomes a sticky situation all around."

In an interview with The West Australian, Henderson denied the rumors that he is the new McDreamy on "Grey's Anatomy." He said he understands the comparison given the timing of the departure of Patrick Dempsey, who played Dr. Derek Shepherd, from the ABC medical drama television series.

While he feels honored to be compared with Dempsey, Henderson said he thinks getting the role of Dr. Nathan Riggs was "really a matter of timing." He explained that "The Red Road," the show he was working on for a couple of years for the Sundance Channel, got cancelled when Dempsey left "Grey's Anatomy."

Henderson pointed out that he knew "Grey's Anatomy" creator Shonda Rhimes because he worked with her on a show called "Off the Map" years ago so she invited him to join the cast of the hit ABC series.

Aside from playing Dr. Nathan Riggs in "Grey's Anatomy" season 12, Henderson is also set to star in "Juveniles," "Miracles from Heaven" and "Hellbent."
