McParland, whose side were chasing their third successive victory, insisted his team should have been awarded a penalty for Michael Townsend's challenge on Rodgers immediately after his goal.
"We got the goal and then had a stonewall penalty," he said. "It was the only thing the referee got wrong.
"Apart from that he was fantastic, but that was a major decision because we would have gone two up.
"The only way I could see Cheltenham scoring was through a long throw or set play and it was disappointing how we gave the ball away for their goal."
