In the [[Training Day (TV series)|CBS television series]] Alonzo is mentioned by Deputy Chief Joy Lockhart when briefing Officer Kyle Craig on sending him undercover at LAPD's Special Investigation Section to investigate Detective Frank Roarke. Frank briefly mentions Alonzo at the end of the first season. The series, starring [[Bill Paxton]] and [[Justin Cornwell]], premiered on February 2, 2017, with a 13-episode run as a [[mid-season replacement]].

Filming for the first season had been completed in December 2016, so the run was not affected by Paxton's death on February 25, 2017, two days after the fourth episode aired.<ref>{{cite web |title=Bill Paxton Had Completed Order For CBS' 'Training Day' Before His Death |last=Andreeva |first=Nellie |website=[[Deadline Hollywood]] |date=2017-02-26 |url=https://deadline.com/2017/02/bill-paxton-death-training-day-cbs-season-1-renewal-1202000300/ |access-date=2023-08-18 |archive-url=https://web.archive.org/web/20230626214653/https://deadline.com/2017/02/bill-paxton-death-training-day-cbs-season-1-renewal-1202000300/ |archive-date=2023-06-26 |url-status=live}}</ref> The lowest rated drama series on CBS that season, it was canceled on May 17, 2017, the same week the season finale aired.<ref>{{cite web |title=''Training Day'', ''Ransom'' Cancelled at CBS |first=Matt Webb |last=Mitovich |website=[[TVLine]] |date=2017-05-17 |url=http://tvline.com/2017/05/17/training-day-cancelled-cbs/ |access-date=2023-08-18 |archive-url=https://web.archive.org/web/20220527005519/http://tvline.com/2017/05/17/training-day-cancelled-cbs/ |archive-date=2022-05-27 |url-status=live}}</ref>
