The long overnight shift at San Antonio Memorial Hospital is over. NBC has decided to can its medical drama "The Night Shift" after running for four seasons.

"We want to thank our amazing creators and executive producers, Gabe Sachs and Jeff Judah, for their dedication and stellar work; a cast and crew that were second to none; and the city of Albuquerque, NM, which graciously opened its arms to us," said NBC Entertainment president Jennifer Salke on Friday, October 13. "For four seasons 'The Night Shift' gave audiences a window to heroic doctors, nurses and all-star medical workers who never hesitated to give their blood, sweat and time to help those most in need."

Throughout the seasons, "The Night Shift" tackled tough issues including veterans affairs, race riots, rape and child prostitution. The series also tackled immigration and political issues.

Created and executive produced by Sachs and Judah, the series followed the E.R. staff at San Antonio Memorial Hospital. The majority of the doctors and staff were back in the civilian world after a few tours in Afghanistan.

Premiering in 2014, the show averaged between 5 and 6 million viewers. The cast included Eoin Macken, Jill Flint and Brendan Fehr. Also starring on the series were Robert Bailey Jr., JR Lemon, Tanaya Beatty and Scott Wolf.

Fehr took to Twitter to share the news. "We all knew it wouldn't last for ever but damn, did we have fun while it did. Love you all. #NightShift Time of death: Friday the 13th," he tweeted.
