Rumor has it Adam J. Harrington is the latest actor to dive into book-to-television adaptation of Cassandra Clare's Mortal Instruments, according to Screen Spy.

Fans are used to seeing stunt training videos from the cast - the actors are learning to kick ass and back flip with the best of them - but the series' stunt coordinator might have let the cat out of the bag with a recent (now deleted) video of Jace Wayland (Dominic Sherwood) allegedly sparing with Michael Wayland (Harrington).

Unfortunately, all evidence of the post has disappeared and Harrington has yet to comment on the rumor.

Shadowhunters will follow the adventures of Clary Fray (Katherine McNamara), a New York City teen who suddenly finds herself wrapped up in the world of the supernatural. A nephilim (half-angel/half-human) and demon hunter by birthright, Clary will have to uncover her mysterious past while working to save her mother and train as a Shadowhunter.

Shadowhunters will come to ABC Family in 2016. Click the video below to see a teaser for the new series.
