Unveiling the True Cause Behind Jeffrey Donovan’s Exit as Detective Frank Cosgrove from Law & Order

“Law & Order” enthusiasts faced another casting change as the show entered its 23rd season, marking the departure of Frank Cosgrove (portrayed by Jeffrey Donovan) and introducing Vincent Riley (played by Reid Scott) as Jalen Shaw’s (Mehcad Brooks) new partner. In November 2023, TV Line revealed that Donovan’s departure was due to irreconcilable creative differences. Currently, without upcoming projects, Donovan’s return in a guest role remains a possibility.

The season opener, “Freedom of Expression,” sheds light on Cosgrove’s exit through a conversation between Riley and Shaw. Shaw remarks, “Great cop, just got jammed up for being too honest about things people aren’t too honest about these days.”

This suggests Cosgrove chose his principles over conforming to the department’s expectations, leaving the force with his integrity intact. Cosgrove’s departure, however, is part of a longer history of cast changes in “Law & Order,” a show known for its evolving lineup since its debut on NBC.

Jeffrey Donovan joined “Law & Order” in 2021 with the series’ revival, and his tenure saw significant cast rotation, even within his brief stint. Initially partnered with series veteran Kevin Bernard (Anthony Anderson), the cast saw a reshuffle from Season 21 to Season 22 when Anderson exited the show, opting not to renew his one-season contract.

Bernard’s exit led to Shaw stepping in from another precinct, setting the stage for Cosgrove and Shaw’s brief but dynamic partnership. Despite these changes, fans can remain optimistic about the “Law & Order” franchise’s stability, which has successfully navigated numerous cast transitions over the years. The hope is that the new partnership between Shaw and Riley will prove enduring.
