Rotherham's first friendly of their pre-season campaign against Leicester was abandoned in the 81st minute due to floodlight failure at Don Valley Stadium.
The Millers were trailing 2-1 to the Championship outfit when darkness fell on the pitch in the late stages of the game and the two sides agreed to call off proceedings.
Rotherham, who returned to training later than most due to last season's play-off exertions, fell behind early on when Paul Gallagher swept home from close range for Leicester but they were soon level thanks to an Adam Le Fondre penalty.
Leicester upped the ante after the break and although Tom Elliott hit the post, Paulo Sousa's men restored their lead thanks to DJ Campbell's low strike.
Boss Ronnie Moore fielded four summer signings in his starting XI with Ryan Cresswell, Tom Newey, Mark Bradley and Elliott all given their bow while Jason Taylor was handed the chance to impress in midfield after spending much of last season on loan at Rochdale.
Rotherham will send a reserve team to Dinnington Town on Wednesday night while they step up their pre-season preparations on Saturday with the visit of Sheffield United.
