Micky Collins admitted Sevenoaks Town paid the price for a poor second half display as the Southern Counties East Football League Premier Division leaders let slip a 2-0 half-time lead to surrender their 100% home record.
Rory Hill’s near 30-yard strike and Jason Thompson’s close-range header put them ahead, with Billy Bennett also hitting the bar twice.
City’s Dave Pilcher pulled one back from the penalty spot, goalkeeper Ben Bridle-Card then pulled off a fine save to keep Town ahead before Jamie Maxted levelled things up with 13 minutes left.
Boss Micky Collins said: “Disappointing. I thought we were good enough in the first half. We were 2-0 up, it should have been four, but you know at this level teams will come out and have a go, and full credit to them."
"They were the better side in the second half and deserved it - and could have gone on and won it - we were hanging on at times - didn’t turn up - and capitulated.”
Injuries to Byron Walker and Bridle Card added to Town’s problems. Striker Walker was helped off with a tendon problem that may need rest, while Bridle-Card faces a scan on a quad muscle problem which could see Collins forced to recruit another goalkeeper.
Bridle-Card needed to be alert as City went close twice early on before Hill put them in front after 11 minutes.
Hill set-up Bennett for his first effort against the woodwork and Walker made the second chance with the bar denying the midfielder again.
Harrison Carnegie was the provider of Town’s second just before the half hour picking out Thompson to head home at the far post.
Mid-table City were a different side In the second half - introducing ex-Town man Darren Marsden, and pressing almost from the first kick after the restart.
Top scorer Pilcher pulled one back after Rob Lawrence was held back, before Carnegie missed out on Town’s third four minutes later firing over the bar.
Substitute Tom Youngs went down in the box inside the last quarter of an hour, but referee Daniel Proctor gave nothing - and a minute later City were level. Substitute Conor Hendricks was involved in the move twice, crossing for left back Maxted to shoot home.
Bridle-Card saved well from Matt Martin, before Bennett ended a frustrating afternoon, heading another late chance over the bar.
