The 10-episode "Grey's Anatomy" spinoff, set in a Seattle firehouse, just added "Dead of Summer."

According to TVLine, his character's name is Ryan. Deadline added that Ryan is a police officer ... so, not a firefighter? Another man of the law, it seems.

The as-yet-untitled series will debut as a backdoor pilot at some point this fall during "Grey's Anatomy" Season 14. The show will then premiere midseason 2018.

"Grey's Anatomy" airs Thursdays at 8 p.m. on ABC.
