Scott Brown believes his Fleetwood Town side were denied a "clear and obvious penalty" in their 2-1 defeat to Bristol Rovers on Monday.
The Celtic hero's side went ahead at Highbury Stadium through Jayden Stockley's first-half header, but Joey Barton's Gas surged back in the second half and hit the front through goals from Lewis Gibson and Grant Ward.
But with the score at 1-1, the Cods had a penalty shout turned down when Shaun Rooney claimed he was fouled by Gibson on the hour mark. Referee Sam Barrrott waved away the appeals and the Gas went ahead five minutes later through Ward's fortuitous winner, with his cross bamboozling goalkeeper Jay Lynch and flying into the net.
