Neel Jani has parted company with the Dragon Racing Formula E team after just two races following a rough debut weekend in the series at last month's Hong Kong E-Prix.

Porsche factory driver Jani was placed in Formula E at Dragon for the championship's fourth season following the closure of the German marque's LMP1 programme at the end of 2017.

Jani endured a difficult first weekend in the series as Dragon ran firmly at the back of the field, finishing 18th in both Hong Kong races, and was left dejected by the team's performance at the end of the opening round.

The weekend was enough to prompt Jani to part company with Dragon ahead of next weekend's race in Marrakesh, confirming the news late on Tuesday night.

"The team and I have decided that it is better for the future of both parties if we end the cooperation," Jani told Swiss newspaper Bieler Tagblatt.

Jani's departure leaves Jerome d'Ambrosio as Dragon's only confirmed driver for Marrakesh, with the team yet to confirm both the news or any possible replacement.

Mike Conway acted as a stand-in for Loic Duval at Dragon for last year's Paris Formula E race, and could be a possible option once again for the team.

While Duval raced for Dragon for two-and-a-half years, a return to the team is thought to be unlikely following a rocky departure at the end of last season.

The decision to quit Dragon leaves Jani with only his LMP1 programme with Rebellion Racing planned for 2018, and also means that Andre Lotterer is the sole Porsche factory driver racing in Formula E ahead of the manufacturer's works entry to the series in 2019.
