The Sky Blues extended their unbeaten run to 12 games in League One, with a 1-1 draw against Rotherham United.
The Millers took the lead midway through the first half when striker Freddie Ladapo tapped home from close range.
However, after the break it was a 13th goal of the season for Matty Godden to draw things level and earn the Sky Blues a share of the points.
