Cody McDonald saw a last-minute header come back off the post as Gillingham were denied the points despite dominating second-half possession in their goalless draw with Oxford.
The in-form Norwich loanee thought he had snatched all the points when he beat Oxford keeper Ryan Clarke from close-range - only for the U's to be saved by the woodwork.
The Gills flew out of the traps and almost took the lead in the third minute when Matt Lawrence's header was saved by Ryan Clarke.
McDonald's strike partner Adebayo Akinfenwa spurned the game's best chance when he pulled a volley wide from eight yards out after Clarke had spilled John Nutter's free-kick.
Oxford's best second-half chance came when Gills midfielder Kevin Maher inadvertently sent Steve MacLean through on goal but Maher was rescued by a tackle from Lawrence.
Substitute Simon Hackney also came close for the visitors but he drilled his effort across the face of the goal in the 79th minute before McDonald's last-gasp chance.
