Cheltenham Town picked up their first point of the season with a resolute display at Portsmouth.
Pompey, who went into the game unbeaten in 14, enjoyed most of the ball at Fratton Park, but they could not find a way past a solid Robins defence.
There was a lengthy stoppage in the second half after a second official was forced off with an injury, leading to a request for anyone in the ground qualified to run the line for the final 35 minutes.
The match eventually restarted, with 21 minutes added on at the end of the 90 and a member of the crowd on assistant referee duty in the Cheltenham half.
Fulham loan wing-back Luciano D'Auria-Henry went on for his debut six minutes into the second half.
Cheltenham play Northampton Town at home next Saturday.
