Veteran midfielder Casemiro gave Manchester United the lead just after the half-hour mark from a controversially awarded corner, with Nottingham Forest claiming the whole ball didn’t go out of play.
Forest went on to take the lead thanks to two goals inside two minutes from Morgan Gibbs-White and Nicolo Savona, only for Amad Diallo to snatch a point late on.
Speaking to Sky Sports after the game, Dyche couldn’t help but reflect on what could have been, slamming the officials for a "really poor decision."
"It's not inconclusive," he said.
"I've seen it back. That's two decisions that are not right that have gone against us.
"They give corners that aren't corners. They gave one last week and one this week. It's a really poor decision.
"That decides a lot. We are fighting for our lives to get up the table."
