Unfortunately, their latest display of loyalty wasn’t rewarded with a win as the home side struggled to break down a resolute Robins defence.
The draw maintains Pompey’s unbeaten start to the season, but with League One experiencing some unexpected results over the weekend, an opportunity was missed to move to the top of the table.
At least the Fratton faithful found some entertainment in the way of a call being made by the club during the second half for a new linesman, after two match officials suffered injury.
Blues fan Julian Browning answered the SOS and ran the line for last 35 minutes of the game.
That will, undoubtedly, have made his day! But what would have made the rest of the home fans’ day will have been a goal. That’s wasn’t meant to be, though, leaving these fans pictures returning home with little to cheer about.
See if you can spot yourself among the 17,454-strong crowd!
