UPDATE: Monday Mornings has also been canceled.
TNT has cancelled Southland after five seasons, issuing the following statement:
TNT has made the difficult decision not to renew Southland for another season. We are enormously proud of Southland, which stands as one of the best police dramas ever made. Executive producers John Wells, Chris Chulack and Jonathan Lisco, along with creator Ann Biderman and our partners at Warner Bros. Television, have given us five seasons of powerful, unforgettable storytelling, for which we are deeply grateful. We also want to thank the amazing cast for their impassioned, no-holds-barred performances, and the production team for their tenacity shooting on the streets of real-world Los Angeles. We wish everyone associated with Southland the very best.
