According to Deadline, CSI Cyber will start airing extra episodes on Wednesday at 10pm until Criminal minds: Beyond borders takes over the slot on March 16th, which means we'll be seeing Cyber twice a week until then.
Elementary will take over the Sunday 10pm slot from Cyber on March 20thwhile new comedy-drama Rush Hour will take over the Thursday 10pm slot from Elementary on March 31st. It is currently unknown as to when Cyber will air it's remaining episodes, but I think it's safe to say that Cyber has been unofficially cancelled
