"What a blessing to be a part of this first and foundational season," the actress writes in a farewell post to the show.

Ifeachor hinted that she was leaving with an Instagram video on Wednesday, July 9, in which she bid farewell to her character, Dr. Heather Collins. Ifeachor starred on the hit medical procedural for its debut season as one of two senior residents in the ER alongside Noah Wyle’s character, attending Dr. Michael "Dr. Robby" Robinavitch.

After suffering a miscarriage earlier in their shift together, Episode 11 of The Pitt showed Dr. Collins confiding in Dr. Robby. To help her better cope, the ER doctor gave Dr. Collins permission to clock out early and turn off her phone, and that was the last time we saw her.
