Paxton died Saturday after suffering complications from surgery. He was 61.
His passing leaves the reboot as his last TV role. Production on the midseason drama was completed in December. Four of the show’s 13 episodes have already aired on CBS.
Described as a reimagining of the Antoine Fuqua feature film of the same name, the series begins 15 years after the 2001 movie left off. It centers on an idealistic young African-American police officer (Justin Cornwell) who is appointed to an elite squad of the LAPD where he is partnered with a seasoned, morally ambiguous detective (Paxton).
Will Beall created the series and executive produces alongside Jerry Bruckheimer, Jonathan Littman, KristieAnne Reed, Fuqua; Danny Cannon and showrunner Barry Schindel.
Cornwell paid tribute to his co-star on Twitter early Sunday:
We were just two guys on top of the world. Rest easy my friend pic.twitter.com/R0ZwB0zv5q

The series debuted Feb. 2 to lackluster ratings and has dipped in the three weeks since its premiere. Training Day was not expected to be renewed and Paxton’s untimely passing makes a second season now increasingly unlikely.
