West Ham striker Andy Carroll says referee Jonathan Moss tried to "even things up" by awarding Leicester City an injury-time penalty on Sunday.
Moss penalised Carroll when Leicester's Jeffrey Schlupp went down in the area, allowing Leonardo Ulloa to convert from the spot to make it 2-2.
The Hammers were awarded a penalty earlier in the game when Wes Morgan pulled back Winston Reid.
Carroll accused Moss of giving "bad decisions" throughout the game.

"It's not acceptable," said the former Liverpool and Newcastle United frontman. "Week in, week out, we've had bad decisions.
"I mean, it is a bad decision. It's not the first time and probably won't be the last. I think he's trying to even it up and a lot of people have said that."
Moss also sent off Foxes striker Jamie Vardy, handing him a second yellow card for diving in the box.
The England international had opened the scoring for the Premier League leaders before Carroll levelled from the spot following Morgan's foul on Reid.
Aaron Creswell then gave the visitors the lead before Ulloa salvaged a point for Leicester to move them eight points clear of second-placed Tottenham, who travel to Stoke on Monday night.
Carroll claims the Hammers would have been occupying a Champions League spot had decisions gone their way this season.
Instead, they are sixth, three points behind Manchester United and seven adrift of Arsenal in fourth
"We could be third and flying," said Carroll. "Now we're still fighting for fourth, fifth spot and we're slipping down by losing these points.
"It is just disappointing and there's nothing we can do about it."
Hammers boss Slaven Bilic added: "It was no penalty. We are gutted, but I am happy with the way we came back."
Leicester will be without Vardy for next weekend's home game with Swansea, with the player due to serve a one-match ban for his red card.
He could also face additional Football Association action for confronting Moss after being dismissed, jabbing his finger towards the official.
