Paulo Sousa's first game in charge of Leicester on English soil ended in farce as their pre-season friendly with Rotherham was abandoned due to floodlight failure in the 81st minute.
The Foxes were leading the League Two outfit 2-1 when darkness fell on the pitch in the late stages of the game and the two sides agreed to call off proceedings soon after.
Sousa, who was appointed as Nigel Pearson's replacement last month, led his new side on a tour of Slovenia last week but took his team to Don Valley for their first public outing in this country.
Paul Gallagher gave the Foxes an early lead when he swept home from close range but Rotherham levelled when Adam Le Fondre converted from the penalty spot. But Leicester grabbed a second after the break when DJ Campbell fired home with a low shot.
Sousa made just one change to the side that beat Slovenian side NK Aluminij, with Gallagher coming in for Matt Oakley, while new signing Tom Kennedy was given another run-out at left-back.
The Foxes continue their preparations for the forthcoming season when they travel to Oxford on Saturday.
