The six-year partnership officially ends after the completion of their last four-day game of the season, against the Titans in Centurion on March 26.
Knights chief executive Johan van Heerden expressed his appreciation for the values and strong foundations the sponsor had brought to the partnership.
“Chevrolet’s support has been absolutely fantastic. They have become part of the family, not only on the professional side but also at the Amateur level,” Van Heerden said in a statement.
The search for a new sponsor was already under way, Van Heerden said.
