Cambridge came from behind to take a point against Forest Green.
Rovers started brightly and took the lead when Reece Styche's low centre was converted by Charlie Griffin.
The visitors had chances to add to their lead but Chris Allen saw a shot cleared off the line and Styche found U's keeper Danny Naisbitt in fine form.
With time running out the hosts levelled through Ashley Carew's penalty after Yan Klukowski fouled Luke Berry in the area.
