A Stewart Greacen header six minutes from time salvaged a point for Derry City away to UCD at Belfield on Friday.
UCD were 1-0 up at half time after Dean Marshall's strike in stoppage-time.
Derry equalised in the 67th minute through Daniel Lafferty who got to Ruairi Harkin's ball to flick over home keeper Gerard Barron.
UCD attacked straight from the kick-off and City keeper Gerard Doherty somehow let Graham Rusk's seemingly tame 20-yard shot slip through his fingers.
The draw against the team two from bottom sees Stephen Kenny's team slip to fourth in the table.
Stephen Kenny's men are overtaken by Sligo Rovers who beat leaders Shamrock Rovers 2-0.
Bohemians beat Drogheda 2-0, Dundalk trounced bottom-placed Galway 6-1 and St Patrick's Athletic had a 1-0 home win over Bray Wanderers.
Derry play UCD again in a League Cup tie on Monday.
