Then as Brown made his way off scuffles broke out as the two benches confronted each other and after a seven-minute delay referee Graham Salisbury showed further red cards to Lincoln substitute Ian Pearce and Cheltenham sub Barry Richardson, neither of whom actually got onto the pitch during the game.
Former Imps player and manager Schofield said: "The incident happened 50 yards away from where we were. How could my bench influence the ref from there? I can't even influence my own players when they're that far away on the pitch.
"I thought it was a straight red card following the foul by Aaron Brown. The referee made the right decision as far as I'm concerned."
